what happens when an electron absorbs a photon

So if the ultraviolet ray and Radio wave get absorbed by the electron together the electron will skip 5 energy levels. The argument is that if a theory must be fine-tuned, then there should be an underlying physical reason for such values. ... What happens when an electron in an atom absorbs a photon? It is considerable that there are still many puzzling aspects of the nature of light. Please also read the short answer I gave to Juan. You can sign in to vote the answer. Graphically, the neutron can be represented by a central proton with a negatively charged shell. The warps may turn into kinetic energy of the absorber, or the warp turns into a clamp, which is a spherical shock front and carries a standard bit of mass because it can temporarily deform its carrier. Einstein wrote in 1951: “All these fifty years of pondering have not brought me any closer to answering the question, what are light quanta?”. Is the modern approach to cosmology fundamentally flawed? http://en.wikipedia.org/wiki/Electromagnetic_spect... http://en.wikipedia.org/wiki/Hydrogen_spectral_ser... atom consists of electrons orbiting around a nucleus. I think theoretical physicists should find this model (QOD) more attractive than the corresponding one from QCD. Beyond the Standard Model: Modern physics problems and solutions. The energy of the full system is, usually, conserved, so the photon's energy is transferred to the possible final state, that, by definition, has n-1 photons. Since this does not happen (no pair of e- e+ is created through its absorption) one must assume that the photon has not been dissociated and therefore endures in an energyless state. Nor does it emit charged pairs. This shell would be in an energetic (massive) state of: m(n) – m(p) = m(shell) = 1.29 MeV. Attempts of a describing a photon's structure shakes the fundamentals of "space-time" considered as a continuum, because, if the photon is an 'extended' structured object and any other particles are 'extended' structured objects too, then what is the phyical meaniing of a 'point', i.e an 'event', in space-time? The asymptotic freedom also explains how these interactions are confined in small regions and you cannot find isolated quarks. Because the act of selecting a theory that way is meaningless. a laser beam. What is the novelty? It needs to gain (-3.4) - (-13.6) = 10.2 eV of energy to make it up to the second energy level.The electron can gain the energy it needs by absorbing light. Following this way one is puzzled by variuos prime numbers which occur in these considerations. (Jr.) On the classical Maxwell-Lorentz electrodynamics, the inertia problem and the Feynman proper time paradigm. Rohrlich F. Self-Energy and Stability of the Classical Electron. If the primary issue put forward is social recognition-it's the wrong place for looking for it. It is believed to be the first ‘classical’ model that contains so many of the accepted quantum features”. It just has lost its oscillatory energy, i.e. In quantum mechanics, "electrons can absorb energy from external sources, such as lasers, arc-discharge lamps, and tungsten-halogen bulbs, and be promoted to higher energy levels. The goal is to try improving it or to go beyond it. The Standard Model uses 6 types of quarks, but since these are “coloured” (they are tri-chromatic) this ends up giving 18 “coloured” quarks. For lattice vibration usually in the far infrared. However, if it transfers all its energy to an absorber, then one irreflexively deducts that the photon has faded away. From a rough classical viewpoint it can be glimpsed that the carrier q- charge would revolve at relativist speeds within the bonding orbital. However, if its structure is vibrating it would consequently have solely energy. Because the known particles have properties beyond that of electric charge, that's why. Apply it to the topic into debate. To think of a photon as an object which has many charged constituents, which can not be observed as 'free' individual objects, but contribute to the interaction of a photon, is somewhat similar to Gell-Mann's quark model for hadrons, which of course had been setup for quite other reasons. According to ordinary theory of special relativity there is unfortunately no rest system of a 'free' photon, which would simplify considerations concerning such an alleged structure of a photon. to imagine of what is going on when a photon interacts with an atom or a single (free) electron (Compton phenomeneon) is to consider a photon as a cloud of electric dipoles (ED). Let us now think about the fact that the electric charge has a single value, while its attached mass is diverse and covers a wide range of discrete values (e.g. From a quantum mechanical approach, if you feel enough confident, just try to modify the Schrödinger equation to adequate it to the specific type of bond proposed. Instead the QOD (Quantum Orbital Dynamics) only resort to the electric charges q- and q+, to which is always associated a wave function Ψ that defines each specific quantum state. in terms of positive and negative electric charges. I guess you have heard a lot about virtual particles, you could say that they are ghost particles. TERE IS A LOT MOR HERE IS A WEB PAGE TO GO AND LOOK FOR THE REST ANSWERS ON THE SUBJECTED http://cas.sdss.org/DR6/en/proj/advanced/spectralt... and it gives you the diagrams in all ok i think you can do your work real well on this web. A hydrogen atom absorbs a photon with a wavelength of 397.1 nm, which excites the atom’s electron. The photons whose quantum energies equal the gap between the ground and excited state are the only ones that will be absorbed by the electron. The point of the question deals with trying to know if the photon only looses its energy in being absorbed, and if its corporeity, body or structure, as you may like better to refer to it, is however preserved. How are bonded two atoms of H to form an H2 molecule? Mass appears when the particle structure goes off its quantum equilibrium state. This is the case of the photon. According to the formula, since the photon has no mass its energy should be null. So, instead to come up with a variety of invented primordial particles, the QOD resorts only on quantum numbers, which provide the diversity of quantum states of the structural orbital of elementary particles. This led to. So, what a more straightforward approach that considering the neutron as the fusion of a proton and an electron. Since this does not happen (no pair of e- e+ is created through its absorption) one must assume that the photon has not been dissociated and therefore endures in an energyless state. But I ask them to be respectful with the fundaments of the model. Thus in vacuum if must be alive, it can never be absorved by one electric charge. They always tell you that you must read their papers that obviously are not well published under peer reviewers. Maths is a specific language created by the mankind in an effort to describe (always incompletely) physical processes. They're the generalization to the weak and strong interactions of what's already known from electromagnetism. the electromagnetic field. We're studying light radiation in Astronomy at the moment, and this question is stumping me. The photon is absorbed and the electron jumps to a higher energy state. It's fascinating how many people focus on the sociological side of science (recognition), rather than the technical-actually learning the craft of doing and understanding the calculations and imagining and realizing the appropriate experiments. What happens when an electron in an atom absorbs a photon? lets say the electron is currently at the Pachen energy level, which is the third one. Yes, I knew about conservation of momentum, thank you. The question is: Would physicists manage someday to find a way of detecting energyless particles. Either way photon energy goes into something else. The photon is not a dipole of anything-and, since it doesn't carry electric charge, it doesn't spontaneously emit photons (there's no such thing as multiphoton vertex-the odd-photon vertex vanishes identically). In order to preserve the debate to end up being chaotic, I will not answer to those that manifestly have not previously read the paper: Space, this great unknown. A pigment molecule in the photosystem absorbs one photon, a quantity or “packet” of light energy, at a time. This tutorial explores how photon energy is absorbed by an electron to elevate it into a higher energy level and how the energy can subsequently be released, in the form of a lower energy photon, when the electron falls back to the original ground state. If a hydrogen atom absorbs a photon of the correct wavelength, its electron will move ____ the nucleus. If the electron jumps from the second energy level down to the first energy level, it must give off some energy by emitting light. In addition, this property of photon (very weak electric dipole) can describe the absorption and emission energy by charged particles. One way of thinking about this higher energy state is to imagine that the electron is now moving faster, (it has just been "hit" by a rapidly moving photon). (fewer photons), Katholieke Hogeschool Sint-lieven, Ghent, Belgium, In §6.3.2 of "Electromagnetism explained by the theory of Informatons-2 (. Or do they suddenly become unskilled outside the QCD framework? A massless particle with no energy would have no momentum either. a variety of quarks and gluons. This of course can not be done simply mixing some parameters and producing some numerical output. It's possible to test all these hypotheses-e.g. Planck agonize for more than 10 years about his idea.related to black body radiation. I found the following cases: E'=E+-c sigma x B, and B'=B-+sigma x E/c, where sigma is the Pauli matrices, and  +- for electron (positron) spin states. George, I wish you the best and I must tell you that I have a great admiration for the people able to create new thoughts and ideas, but with enter in the details and defend them with clear arguments. In the analogy, the spring stands for the bonding force of the dipole. If you just fool around without contributing efficiently to the issue, your employer may just fire you. Differentiation between the origin of energy and that of mass, of the paper: Space, this great unknown. Their QCD representation would be just a very coarse and counterfeit approximation to their structure, with the disadvantage of not applying to all particles, and thus not being a unitary approach. There's nothing to defend-and the qualifiers bestowed on descriptions of natural phenomena are meaningless-as are opinions. How photon will decide when to behave like a wave or particle? Suppose you are working in a research group and a very specific research must be carried out. It would be another breakthrough to find out the quantization of the deuteron bonding shell. Since I am somewhat old my intention was to offer the Orbital Model as an intellectual heritage to those that would like to further work on it in order to move forwards its development. To think of what might be beyond the "Standard Model" based on mathematical and ontological non-convincing QFT-phantasies has already started for more than 20 years ago. According to Bohr, what happens to the electron when a hydrogen atom absorbs a photon of light of sufficient energy? Where do photons go in absorption? The relations between the electric charges of quarks and leptons are, similarly, known to be fixed by the consistency of the electroweak interactions. Thus the photon vanishes. I do ask for intellectual discipline. I’ve never encountered that concept. photons, satisfy the equation, where gamma = 1 / sqrt( 1 - v^2/c^2) , and therefore, Expanding (gamma-1) in terms of v/c then leads to. And all its properties can be deducted from that, taking into account how the week interaction Hamiltoniam acts on these states. Oppositely to the strategy of QCD, the QOD (Quantum Orbital Dynamics) resorts on a single primary element, the integer electric charge, and the variety of elementary particles is regarded as corresponding to the variety of quantum states that the electric charge can acquire. What happens to an electron when it emits a photon? Why shouldn’t we extend this pattern based solely on the electric charge to all elementary particles, so we would get a unitary conception of the different building blocks of matter? An atom with 6 protons and 6 neutrons is a carbon atom, and an atom with 6 proton and 7 neutrons is also a carbon atom. According to the orbital model, although energy and mass are associated, with one exception represented by the photon, they do not have the same origin. When they fly away being aligned we call it a beam, e.g. "Absorption" by an atom then can be thought of a 'join' of the dipole cloud of the photon with the dipole clouds of the electrons and protons 'inside' the atom, which results in an 'excited state' of the atom, i.e. The interaction of protons with protons and neutrons in nuclei  isn't described by electromagnetism-it's described by  forces that aren't electromagnetic, since these can be subtracted out now and something's left. Thus my question is really three parts. in quanta or photons). In such a case it would be absorbed by one excited state of one electric charge as it happens with one electron of one a atom (i.e. Have you ever thought about why photons are stable and travel millions of years through space without dissociating. Since the spin of the neutron shell is taken equal to 1, thus the spin of the neutron is 1/2. first time submission experiences). In a semi-classical approach I have myself treated the muon within the framework of the harmonic oscillator, obtaining a very close mass value to the experimental one. To review the standard model, the first step is reviewing the structure of fundamental particle. To those interested in the Orbital Model: Let’s start to work, now that the fundaments of the model have been expressed. I will not let the debate evolving into a mess. When a photon is absorbed by an electon it gives up, What is this “structural bonding energy” of a photon that you speak of? Sorry but let me to come back to my previous question. It has then mass and energy. Scheme of the absorption of light, by a black body or a polarizer, Fig. The speed c of an electromagnetic wave is determined by the constants of electricity and magnetism. But one thing is its energy that it does loose and another thing is its corporeity, which it does not loose. "On the question of the electromagnetic momentum of a charged body". Words are cheap-where's the ``alternative'' model of the photon that (a) is consistent with all that's known about it and (b) predicts something that isn't? If you don’t see it feasible, it is your free choice. Definitely you should look for another forum. Do you believe that extraterrestrials might exist? The photon itself ceases to be. How do you explain the repulsion of the electric charge in the nucleus? Ordine degli ingegneri della provincia di Ancona. The parameter spaces correspond to versions of the quaternionic number system. What is then the geometrical meaning of parts in the gluon-like pairs? And from this , you can get a lot of information about the star you are studying. Let’s put it in other terms. With others words, the characteristic process ensures both the coherent movement of the footprint, and it establishes the (spectral) binding of the components. One must comes up with a structural model and after while check if it survives experimental check up. AND HERE IS A NOTHER http://en.wikipedia.org/wiki/Photon. And the only thing that matters is that it be internally consistent. J. Phys. The characteristics of these chaotic fluctuations are influenced by the interaction process of a photon with an atom or, for example, with 3 atoms or molecules specifying the plain surface of a piece of solid resulting in a reflection. Again the characteristic function acts as a displacement generator, which ensures that the conglomerate moves as a single unit. This doesn't mean that one is computing the mass of the muon, however and there's a reason for that, that's well understood. 3, p. 187-212, and by Rodrigo Medina in the work "Radiation reaction of a classical quasi-rigid extended, particle", J. Phys. Up to now I have only seen theoretical answers to the question asked. When detaching from its core proton the shell acquires the quantum state of an electron (0.51 MeV/c2) at the time that part of the excess energy is liberated into the emission of an anti-neutrino. Maxwell formulated dynamical theory of the electromagnetic has showed light is an electromagnetic wave. The dissociation of very energetic photons is experimentally well settled. Nature has no idea of maths, It just knows about physical interactions. In the Orbital Model, the neutron is seen as composed of a core proton and a negative shell of spin 1 and mass 1.29 MeV/c2. I can add myself, based on twenty years of experience, that the Standard Model is sustained by a constant counterfeit propaganda, and by the SM advocate referees who censure any intent of publication diverging from this surpassed model. So, it is an interesting singular case because it challenges our concept of mass and energy, and their relationship. This transaction transfers by electromagnetic means, a quantum of looping, Please, read first the recommendations at the very beginning of the debate. OK. Let us extend this reasoning to the photon. Approaches can endlessly been improved. The opposite happens when an electron emits a photon. There are an infinite number of energy levels but only six of them are named, and there names are: Lyman, Balmer, Paschen, Brackett, Pfund, Humphreys. As we know it has no mass but energy, representing a unique case given that it violates the famous mass-energy equivalence (E = m c2). When a photon with appropriate energy comes by, the electron can take the energy and get kicked into a higher energy level. You say: This process can be described by the action of an operator on the state of n photons, But you add: that, indeed, destroys a photon and that's why it's called an annihilation operator. Introduction: When an electron absorbs a photon, it gains energy, causing it to move to a higher orbit. But the diversity of vibrational frequencies it can acquire grants it a continuous spectrum of energies. I suppose that he has one idea of what he wants to know about this question. In the case it would still wear an infinitesimal amount of energy it would still exist. What happens to the photon when it is absorbed? it does not “shine” anymore, and hence it cannot be seen anymore. So, should we come up with two logics, one for the bulb and an opposite one for the photon. (The description of natural phenomena is mathematical, nothing more and nothing less. When the electron is pushed off, it wanders around until it latches itself to another lone proton and starts orbiting it, this is called Recombination. That energy is not a binding enegy, it just has that energy. If you try to go deeper in the issue, you have to ask yourself why very energetic photons, above 1.02 MeV do not dissociate into a pair e+ e-. This time the characteristic function is the superposition of the characteristic function of the stochastic processes that generate the foot prints of the components. Fig. They do not oscillate anymore, so how could we still detect them? Particle of light. To achieve progress in understanding and describing the very nature of a photon in a reasonable and convincing way one must have the courage to get rid of the blinders, flaws and fallacies of traditional physical theories. The difference in ordering symmetry explains the short list of electric and color charges that exist in the standard model. Scheme of the frequency doubler set-up, Fig. The analogy is not so simple to follow, at least for me. Observers can only access information that comes from the past and it is transferred to them via vibrations and deformations of the continuum that embeds both the observed event and the observer. There are open questions in physics-but how to compute the magnetic moment of particles is no longer one of them. Metaphysical expressions don't count-unless they can be identified with  calculations, in which case, personal opinions don't matter (the word ``adversity'' is meaningless in this discussion). Your radically conformist standpoint is well known, so it would be a huge deliverance if you would defend it in a traditionalist site where no doubt you would be much applauded. It is based on a specific mathematical map of the structure of elementary particles, which relies on the diverse quantum states that their orbital structure can take. How does this sound? It is a very fundamental point of the model in resorting only to quantum states to account for all elementary particles. and many other things of particle physics which physicists of the 21-th century consider to be 'true'. So, we finally have 36 different quarks. But we have also 8 different types of gluons for the bonding task. Well, we could make a parallelism with the atom, which may have different excited states, i.e. How to setup the relationship to a 'spin'-based definition is one of the problems of Hypotron Theory which are not yet solved completely. One way to solve the problem is just to assume that they have no structure as some do (at the very first the atom was seen as just a ball). The trick is that once the photon excite one particle to a higher level, if the selection rule forbbids the decaying then the photon is obligued to be at such state. The photon only can be kept during a certain time "alive" in a metastate in molecules, atoms or nuclei. The electron stays in the first excited state, having absorbed the photon. But in its absorption by a material it just loose the energy related to its wavelength without loosing its structural bonding energy of 1.02 MeV, energy that should be brought by the absorber in order to get dissociated. And the decay of the neutron isn't mediated by electromagnetic interactions-if it were it would be completely different. Then, the electron relaxes in a single step and emits a photon with the same energy as the absorbed photon. For instance, the electric dipole approximation is always forbidden and in principle the photon could remain "alive" for ever. I cannot re-explain too often what has been already explained in the diverse papers. I think it's clearest to interpretate that a photon exists only at emissions and absorptions, not between them when it's a wave packet which can interfere diversely and resonate coherently with massive particles. It can't see where else it could go... What you are saying suggests to me that, for perfect accuracy, photon mass. In addition, new experiment shows that the probability of absorption at each moment depends on the photon's shape, also photons are some 4 meters long which is incompatible with unstructured concept that means trying to describe the structure of photon is reasonable. I think that the best way to look at it is to ask to oneself: would not I be loosing an opportunity to devise something fundamentally new. 4. The term information is quite vague, you should define its content. And a radio wave with a long wavelength meaning less energy can cause the electron, lets say, to only skip 1 energy level. Electrons can jump from one energy level to another, but they can never have orbits with energies other than the allowed energy levels.Electrons in a hydrogen atom must be in one of the allowed energy levels. It does not have an option to take part of the photon - just like a square peg does not have an option to fit into a round hole. Waves cannot do that. Join Yahoo Answers and get 100 points today. The electrons orbits a proton. If it is in the second energy level, it must have -3.4 eV of energy. Besides, wrong predictions are discarded, so we are left only with those that presumably coincide with experimental detections. It is also interesting to note that Hypotron Theory predicts the existence of a boson with charge 3, called 'tripolon' (everything must ae a name!). How a light source emits (or absorbs) a photon? But what really happened to it. However, the direction of the imaginary part of the gluon-like pair must be perpendicular to the direction of the anisotropy of the quark. What is really peculiar is the Quanglement, which creates twin photons during emission. x: cross product and sigma is 3x3 Pauli matries. The platforms on which elementary particles reside inherit these properties from the parameter space that occupies the platform. The difference stands in that the two charges q+ and q- acquire their quantum state as e+ and e- only after they get free once the photon is dissociated. 3. It would be a huge breakthrough to find out the quantization of the neutron shell. However it would be more constructive, if you have clearer views, to start working on them. Why its magnetic moment has a value of -4.70589 nm and not another one? While the sociology of the two endeavors has diverged, one ought to know better-if one's studied physics. Strictly with the same token the low energy photons also dissapear in reactions., proceses which very excited. Measuring its spin ; the neutron shell, what a photon of the 'continuum ' of flat 'space-time ). You compute the magnetic moment of a core proton wrapped by the absorber you an example.
