Problem
A photocell initially receives light of frequency ν (ν>ν0) and intensity I. At zero applied voltage, the photocurrent is I1. Next, two changes are made simultaneously: (i) The frequency is increased to 1.2ν. (ii) The intensity is reduced to 0.5I. Which of the following is the correct prediction for the resulting saturation photocurrent (Is) and stopping potential (V0) compared with their initial values?
(a) Is remains the same, V0 increases
(b) Is decreases, V0 increases
(c) Is increases, V0 increases
(d) Is decreases, V0 remains the same
