The figure shows a plot of photo current versus anode potential for a photo sensitive surface for three different radiations. Which one of the following is a correct statement?
-
- Curves (1) and (2) represent incident radiations of same frequency but of different intensities.
- Curves (2) and (3) represent incident radiations of different frequencies and different intensities.
- Curves (2) and (3) represent incident radiations of same frequency having same intensity.
- Curves (1) and (2) represent incident radiations of different frequencies and different intensities.
Correct Option: A
Retarding potential depends depends on the frequency of incident radiation but is independent of intensity.
