Problem

A metal surface is illuminated with monochromatic light of fixed frequency that is above the threshold frequency. Predict how the photocurrent–voltage curve will change if the intensity of the incident light is doubled while the frequency remains the same. State the effect on (i) the saturation current and (ii) the stopping potential.
