i) Type of metal
ii) Frequency of radiation
iii) Intensity of radiation
1. Work function of the metal - photoelectrons are emitted at different velocities with the maximum being processed by the ones at the surface
2. Energy of protons
3. Frequency of the metal incident radiation - the cut-off potential for each surface is directly proportional to the frequency of the incident radiation.
4. Intensity of radiation falling on the metal - the rate of emission of photoelectrons is directly proportional to the intensity of incident radiation.
