Question

In photoelectric effect the number of photo-electrons emitted is proportional to

Easy

A

intensity of incident beam
B

frequency of incident beam
C

velocity of incident beam
D

work function of photo cathode

Solution

By increasing the insincerity of incident beam, the number of emitted photo-electrons can be increased. Hence number of photo-electrons emitted is proportional to the intensity of incident beam,
