Photoelectric Experiment: Intensity, Stopping Potential & Graphs

In a photoelectric experiment, if the intensity of incident light is doubled and the frequency is kept slightly greater than threshold frequency, then the saturation photoelectric current

Show answer and solution

Answer: (c)

Above threshold, saturation current $\propto$ number of photons per second $\propto$ intensity.
Doubling intensity doubles the current.
So the answer is (c) is doubled.
