Draw a plot showing the variation of potoelectric current with collector plate potential for two different frequencies, `v_(1) gt v_(2)`, of incident radiation having the same intensity. In which case will the stopping potential be hgiher ? Justify your answer.

Text Solution

Verified by Experts


Stopping potential is more for the corresponding to frequency `v_(2)`.
Stopping potential is directly proportional to the frequency of incident radiation.
