Photoelectric effect supports quantum nature of light because

Options

  1. Athere is minimum frequency of light below which no photoelectrons are emitted
  2. Bthe maximum energy of photoelectron depends only on the frequency of light and not on its intensity
  3. Cphotoelectric effect is an instantaneous process
  4. Dall the above choices are correct

Correct answer

D. all the above choices are correct

Step-by-step solution

The three experimental facts listed under (a), (b) and (c) cannot be explained on the basis of wave theory of light. All these facts support the quantum (photon) nature of light.
