If p is the momentum of the fastest electron
ejected from a metal surface after the irradiation
of light having wavelength , then for 1.5 p
momentum of the photoelectron, the
wavelength of the light should be:
(Assume kinetic energy of ejected
photoelectron to be very high in comparison
to work function)
