A photoelectric cell is connected to a source of variable potential difference, connected across it and the photoelectric current resulting `(muA)` is plotted against the applied potential difference (V). The graph in the broken line represents one for a given frequency and intensity of the incident radiation . If the frequency is increased and the intensity is reduced, which of the following graphs of unbroken line represents the new situation?

A

A

B

B

C

C

D

D

Text Solution

Verified by Experts

The correct Answer is:
D
Intensity reduced therefore saturation current reduced. Frequency increased, therefore stopping potential increased.
