WebSpontaneous emission is the process in which a quantum mechanical system (such as a molecule, an atom or a subatomic particle) transits from an excited energy state to a lower energy state (e.g., its ground state) and emits a quantized amount of energy in the form of a photon.Spontaneous emission is ultimately responsible for most of the light we see all … WebThe emitted radiation has a frequency corresponding to the energy light would have if it were a particle of E = hf colliding with the electron. ... Notice that at first glance we seem to be saying something very incoherent. A wave cannot have a wavelength, even approximately, unless it is spread out over distances large compared with the ...
