Question
CBSEENPH12039268

Draw a plot showing the variation of photoelectric current with collector plate potential for two different frequencies, v1 >v2 , of incident radiation having the same intensity. In which case will the stopping potential be higher? Justify your answer. 

Solution

The plots showing the variation of photoelectric current with collector potential is shown below.

Stopping potential is directly proportional to the frequency of incident radiation.
