Does the ‘stopping potential’ in photoelectric emission depend upon (i) the intensity of the incident radiation in a photocell? (ii) the frequency of the incident radiation?

(i) The stopping potential does not depend on the intensity of the incident radiation, as intensity affects the number of photoelectrons, not their energy.
(ii) The stopping potential depends on the frequency of the incident radiation because higher frequency photons impart more energy to the emitted electrons, requiring greater potential to stop them.
