Does each incident photon essentially ejcted photoelectron?

A UV light of wavelength 320 nm is incident on a photosensitive surface and photoelectrons are emitted from it . The stopping potential is 0.48 V. Find (i) the energy of each incident photon. (ii) maximum kinetic energy of a photoelectron. (iii) work function of surface.

When metal surface is incident with photon after how much time photoelectron are emitted?

10^-3 W of 5000A light is directed on a photoelectric cell. If the current in the cell is 0.16muA , the percentage of incident photons which produce photoelectrons, is
