Photoelectric effect supports quantum nature of light because, 1. There is a minimum frequency of light below which, no photoelectrons are emitted. 2. Electric charge of photoelectrons is quantized. 3. Maximum kinetic energy of photoelectrons depends only on the frequency of light and not on its intensity. 4. Even when metal surface is faintly illuminated, the photoelectrons leave the surface immediately.
