A graph plots photocurrent against anode potential for three incident radiations a, b, c. Which statement is correct? [Image]

G1 Physics · Accepted Answer

Two curves that reach zero current at the same stopping potential correspond to the same frequency (same maximum kinetic energy). Different saturation currents reflect different incident intensities. In the diagram this describes a and b. Answer: B.
