Problem
Two light beams fall separately on the same metal surface.
(i) Beam A has frequency 1.2ν0 and intensity I0, where ν0 is the threshold frequency of the metal.
(ii) Beam B has frequency 1.5ν0 and intensity 2I0.
For each beam, predict whether the saturation current and the stopping potential will be greater, smaller or equal compared to the other beam. Give brief reasons for each comparison.
