Photoelectric effect When light of sufficiently small wavelength is incident on a metal cathode, it may emit electsons called photoelectrons. This is called photoelectric effect. Above threshold frequency, the stopping potential and hence the energy of the photoelectrons is directly proportional to the frequency.
