Question

Draw a plot showing the variation of photoelectric current with collector plate potential for two different frequencies, $ν_1 > ν_2,$ of incident radiation having the same intensity. In which case will the stopping potential be higher? Justify your answer.

✓

Answer

Stopping potential is more for the curve corresponding to frequency $v_1$ Stopping potential is directly proportional to the frequency of incident radiation.
Alternate Answer
The maximum energy(of the emitted photoelectrons) increases with an increase in the frequency of the incident radiation.
