Can photons combine
WebSep 6, 2013 · A photon can spontaneously degenerate into a particle with mass and its antiparticle in a process known as pair production. In this process, the energy of the photon is completely transformed into the … WebIn the anhiliation process you have two vertices with photons. It means there is a virtual electron/positron involved in the process. So I suppose in some sense, you can have spontanious pair production but it requires the electron-positron pair produced are virtual, and hence short lived. – user3728501 Jun 18, 2024 at 12:10

WebMar 2, 2016 · When it drops from the conduction band into a hole in the valence band, that's called 'recombination'. By conservation of energy, we can expect to see a single photon that can escape the material as light (of a hue that represents the energy difference in … WebA photon will be absorbed if its energy, given by E = h ν, fits some energy level of the atoms, (molecules, system) it hits and then a re-emitted photon may change both direction and energy with respect to the originating one, i.e. if the reflected one changes frequency because of the re-emission,and loses the phase it cannot contribute to a …
WebWhen a photon is absorbed by chlorophyll, the energy level of some of the electrons in the pigment is raised. Which of these are possible after that? The energy can be released as heat. The pigment can fluoresce or phosphoresce. The absorbed energy can eventually be stored in chemical bonds. WebThe electron can absorb photons that will make it's charge positive, but it will no longer be bound the the atom, and won't be a part of it. For example at -10ev, it can absorb, 4eV (will move to -6eV), 6eV (will move to -4eV), 7eV (will move to -3eV), and anything above 7eV (will leave the atom)
