Question

Draw graph showing variation of photoelectric current with applied voltage for two incident radiations of equal frequency and different intensities. Mark the graph for radiation of higher intensity

Answer 1

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.
