Photoelectric effect supports quantum nature of light because

A

there is minimum frequency of light below which no photoelectrons are emitted

B

the maximum KE of photoelectrons depends only on the frequency of light and not on its intensity

C

even when the metal surface is faintly illuminated by light of wavelength less than the threshold wavelength, the photoelectrons leave the surface immediately

D

electric charge of photoelectrons is quantized

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
Existence of cut off frequency and photoemission takes place even when intensity is low.

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.
