A photoelectric experiment is performed ...

A photoelectric experiment is performed at two different light intensities `I_(1) and I_(2) (I_(2) gt I_(1))`. Choose the correct graph showing the variation of stopping potential versus frequency of light.

Text Solution

Verified by Experts

The correct Answer is:

The value of stopping potential depends on the maximum kinetic energ9y of the photo-electron and thus it is independent of the intensity of light. Therefore, none of the graph shown is correct. The correct graph is shown in the figure.
