The emission of electrons from a metal surface exposed rto light radaition of appropriate wavelength is called photoelectroic effect .The emmited electron are called photo=-weklectron work function of threshold energy may be defined as the minimum amount of energy required to ejercted electron from a most surface .According to Einstein Maximum kinetic energy of ejected electron = Aborbed energy - Work function (1)/(2) mv_(max)^(2) = h(v) - h(v_(n)) = hv [(1)/(lambda) - (1)/(lambda_(n))] Where v_(n) and lambda_(0) are thereshold frequency and threshold wavelength respectively Sopping potential : it is the miximum potential at which the photoelectric current becomes zero if V_(0) is the stopping potential eV_(0) = h(v- v_(0)) In the photoelectric currect effect the shape of strainght line graph between stopping potential (V_(0)) and frequency of incident light (V) gves

Statement I A metallic surface is irradiated by a monochromatic light of frequency v gt v_(0) ( the threhold frequency ). The maximum kinetic energy and the stopping potential are K_("max") and V_(0) respectively. If the frequency incident on the surface is doubled, both the K_("max") and V_(0) are also doubled. Statement II The maximum kinetic energy and the stopping potential of photoelectrons emitted from a surface are linearly dependent on the frequency of incident light.
