Assertion : Photoelectric effect supports the quantum nature of light. Reason : Photoelectric emission is instantaneous.

Statement-1 : Photoelectric effect supports the particle nature of light. That means light is not a wave in this case. Statement-2 : The particle nature and the wave nature of light coexist, what we feel is the nature that is dominating at a particular situation.

Assertion : The threshold frequency of photoelectric effect supports the particle nature of light. Reason : If frequency of incident light is less than the threshold frequency, electrons are not emitted from metal surface.

Assertion: Photoelectric effect proves the particle nature of light. Reason: Photoemission starts as soon as light is incident on the metal surface, provided frequency of incident light is greater than or equal to the threshold frequency.
