An electron is trapped in an infinitely deep one-dimensional well of width 0,251 nm. initially the electron occupies the n=4 state.
(a). suppose the electron jumps to the ground state with the accompanying emission of a photon. what is the energy of the photon?
(b). find the energy of other photons that might be emmited if the electron take other paths between the n=4 state and the ground state!



Photons are the elementary particles in electromagnetic phenomena. Usually photons are considered as carriers of electromagnetic radiation sorry i only can answer question number 1
