Question

Why photoelectric effect cannot be explained on the basis of wave nature of light ? give reason.

Answer 1

Answer:

Wave nature of radiation cannot explain the following:

1. The immediate ejection of photoelectrons.
2. The presence of threshold frequency for a metal surface.
3. 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 (failed to explain many phenomena such as black body radiation and photoelectric effect) on the basis of wave nature of light.
