What is the effect of the intensity of incident radiation on the photoelectric current, for a given emitter material and p.d across the photoelectric cell ?

Text Solution

Verified by Experts

For a given emitter and p.d. across the photoelectric cell, the photoelectric current is directly proportional to the intensity of the incident radiation, provided the incident frequency is greater than or equal to the threshold frequency for the emitter material.
