Solution
Wave nature of radiation cannot explain the following:
(i) The instantaneous ejection of photoelectrons.
(ii) The existence of threshold frequency for a metal surface.
(iii) The fact that kinetic energy of the emitted electrons is independent of the intensity of light and depends upon its frequency.
Thus, the photoelectric effect cannot be explained on the basis of wave nature of light.
