Photoelectric Experiment: Intensity, Stopping Potential & Graphs

Which of the following options represent the variation of photoelectric current with property of light shown on the x-axis?

Show answer and solution

Answer: (c)

Above threshold, photocurrent $\propto$ intensity (number of photons): graph A is correct, B is wrong.
Photocurrent does not increase with frequency; frequency only changes the kinetic energy. So C and D are wrong.
So the answer is (c) A only.
