Question

how does the stopping potential of a photosensitive material vary with intensity of incident radiation​

Answer 1

Stopping potential and its relation with the intensity of incident light:-

• The minimum negative potential that is given to a plate for which the photocurrent becomes zero is called the stopping potential.
• The stopping potential is independent of its intensity for a given frequency of incident light.
• Also, the maximum kinetic energy is independent of the intensity of the incident radiation but depends on the frequency of the source of light and the nature of the emitter.
