The figure shows a plot of photo current versus anode potential for a photosensitive surface for three different radiations. Which one of the following is a correct statement ?

A

curves a and b represent incident radiations of different frequencies and different intensities

B

curves a and b represents incident radiations of same frequency but of different intensities

C

curves b and c represents incident radiations of different frequencies and different intensities

D

curves b and c represents incident radiations of same frequency having same intensity

Text Solution

Verified by Experts

The correct Answer is:
B
Stopping potential is same for a and b, hence their frequencies are same. The maximum current values are different for a and b so they will have different intensities
