C

even when the metal surface is faintly illuminated, the photoelectrons leave the surface immediately

D

all of these.

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.
