9. Does stopping potential depend upon work function of
the photo-sensitive material ?

Answer:This may help you
Explanation:
Stopping potential depend upon frequency of incident light. Photoelectric current stops below a particular frequency of incident light. The frequency is known as threshold frequency. Work function is the characteristic of a photosensitive material.
The stopping potential depends on the frequency of the incident light and not on the intensity. This is for the photo electric effect. The stopping potential depends on the kinetic energy of the electrons, which will be affected only by the frequency of the incoming light and not by its intensity.
The stopping voltage (or stopping potential) refers to the voltage difference required to stop electrons from moving between plates and creating a current in the photoelectric experiment. The minimum amount of energy that is required to eject an electron from the metal surface is known as the work function.
