    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? Retarding potential Anode potential

    A)  Curves a and b represent incident radiations of different frequencies and different intensities

    B)  Curves a and b represent incident radiations of the same frequency but of different intensities

    C)  Curves b and c represent incident radiations of different frequencies and different intensities

    D)  Curves b and c represent incident radiations of the same frequency having the same intensity

    Correct Answer: B

    Solution :

     From the two graphs we can conclude that for the graph in question curves a and b represent incident radiations of the same frequency but of different intensities.
