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

A

there is a minimum frequency below which no photoelctrons are emitted

B

the maximum kinetic energy of photoelctrons depends only on the frequency of light and is independent of intensity.

C

even when the metal surface is illuminated with very small intensity the photoelectrons ( if `v gt v_(th)`) leave the surface immediately

D

electric charge of the phtoelectrons is quantized

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.

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.

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.

Statement (A): Alkali metals exhibit photo electric effect when they illuminated with visible light. Statement (B): Photoelectric emission is also like thermionic emission.

Assertion : Photoelectric current depends on the intensity of incident light. Reason : Number of photoelectrons emitted per second is directly proportional to intensity of incident radiation.
