Question

A photoelectric experiment is performed at two different light intensities I1 and I2 (I2 > I1) . Choose the correct graph showing the variation of stopping potential versus frequency of light. (A) Option 1

(B)

(C)

(D) None of these

The value of stopping potential depends on the maximum kinetic energy 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. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-6mauhdxlizvr.png" />
