three characteristics features in photoelectric effect that cannot be explained on the basis of wave theory of light,but can be explained only using Einstein equation are :
1 The energy of photoelectrons liberated is not controlled by the intensity of incident light . which should be case if light was wave theory . as in a wave the amplitude of wave in increased with intensity .
2 The emission of electrons has no delay which is not supported by the wave theory .
3 The emission of photoelectrons happens after a threshold frequency which should not happen according to wave theory .
