Question

Mention two observations which could not be explain by the wave nature of electromagnetic radiations.

Answer 1

Answer:

Explanation:

Photoelectric effect in light cannot be explained by wave nature of light. It can only be explained by particle nature of light, because it involves emission of photoelectrons by the action of photons on a metal surface. This can only possible if light is to be considered of particle nature!
