Photoelectric effect When light of sufficeintly small wavelength is incident on a metal cathode, it may emit electons called photoelectrons. Above threshold frequency the stopping potenital and hence the energy of the photoelectrons are directly proportional to the frequency. in the given figure, we see the variation of stopping potential with the frequency of incident radiation for three metals A, B and C. Which of these metals A, B or C are suitable for photoelectric cell?
