If the intensity of incident radiations in a photocell is increased, how does the stopping potential vary?

State the influence of work function on kinetic energy of electrons emitted in a photocell. If the intensity of the incident radiation is doubled, what changes occur in the stopping potential and photoelectric current?

State the dependence of work function on kinetic energy of electrons emitted in a photocell. If the intensity of the incident radiation is doubled, what changes occur in the stopping potential and photoelectric current?

If the frequency of incident radiations is equal to the thresold frequency, what will be the value of stopping potential?

if the maximum k.E. of electrons emitted by a photocell is 4 eV, what is the stopping potential?

Explain the effect of increase of intensity of incident radiation on photoelectric current with suitable graphs.

The figure shows the stopping potential for the phototelectron versus (1/lambda) graph for two metals A and B, lambda being the wavelength of incident light If the distance between the light source and the surface of metal A is increased, how will the stopping potentail for the electrons emitted from it be affected? justify your answer.
