Draw graphs showing variation of photoelectric current with appliedvoltage for two incident radiations of equal frequency and differentintensities. Mark the graph for the radiation of higher intensity.

Answer»

Let a and b be two radiations with same frequency but different intensities.

These two radiations have same stopping voltage.

The higher the intensity the more the photoelectric current emitted.

Let a be of higher intensity and b of lower intensity then the graph is as shown in the image.
