I've got a question for you all. if there is a wave-function for a single particle, such as a photon.. and there is a wave-function for an electron.. "A wave function in quantum mechanics describes the quantum state of an isolated system of one or more particles. There is one wave function containing all the information about the entire system, not a separate wave function for each particle in the system. Its interpretation is that of a probability amplitude. Quantities associated with measurements, such as the average momentum of a particle, can be derived from the wave function." and electrons EMIT photons when dropping down in an fermi level, energy.. emitting radiation as the photon.. does the wave-function for the photon not exist WITHIN the wave-function of the electron ? does it become part of the wave-function of the electron ? it surely changes the wave-function of the electron.. either by momemtum or angle ... but doesn't the wave-function of the photon somewhat exist within the electrons ?
