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

A

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

B

the maximum K.E. of photoelectrons depends only on the frequency of light and not on its intensity.

C

Assertion: Photoelectric effect supports the quantum nature of light. Reason : Electric charge of photoelectrons is quantised.

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.
