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?

Options

ACurves $a$ and $b$ represent incident radiations of different frequencies and different intensities
BCurves $a$ and $b$ represent incident radiations of same frequency but of different intensities
CCurves $b$ and $c$ represent incident radiations of different frequencies and different intensities
DCurves $b$ and $c$ represent incident radiations of same frequency having same intensity

Correct answer

B. Curves $a$ and $b$ represent incident radiations of same frequency but of different intensities

Step-by-step solution

From the two graphs we can conclude that for the graph in question curves

a

and

b

represent incident radiations of same frequency but of different intensities.
