Question

do all electrons emitted in photoelectric effect have same kinetic energy? if not, why?​

Answer 1

Answer:

No. Each electron energy possessed by an ejected electron can either be the same or different from the other because when a photon energy is absorbed by an electron, part of the energy is used to overcome the binding energy. The extra energy is the one used to release the electron.
