Emission of electrons in photoelectric effect is possible if

A

Metal surface is lightly polished

B

The incident light is of sufficently high intensity

C

The light is incident at right angles to surface of the metal

D

The incident light is of suffciently low wavelength

Text Solution

Verified by Experts

The correct Answer is:
D
When the frequency of incident radiation increases I.e., th e incident light is of low wavelength the electrons are emitted in photoelectric effect.
