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

  1. ACurves a and b represent incident radiations of different frequencies and different intensities
  2. BCurves a and b represent incident radiations of same frequency but of different intensities
  3. CCurves b and c represent incident radiations of different frequencies and different intensities
  4. 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.
