WebFeb 12, 2013 · The increase of the light frequency results in an increase of the intensity of the current that flows trough the circuit. They were judging this wrong. This sounds very wrong. An increase in frequency by itself shouldn't affect the current at all. The current would be the amount of charge coming off of the metal per unit time.
