  • question_answer
    The figure shows a plot of photocurrent v/s anode potential for a photo sensitive surface for three different radiations. Which one of the following is a correct statement?

    A) Curves and represent incident radiations of same frequency having same intensity

    B) Curves and represent incident radiations of different frequencies and different intensities

    C) Curves and represent incident radiations of same frequency but of different intensities

    D) Curves and represent incident radiations of different frequencies and different intensities

    Correct Answer: C

    Solution :

    [c] \[hv={{\phi }_{0}}+e{{V}_{0}}\] Here \[{{V}_{0}}\] is same for [a] and [b] represent incident radiations of same frequency but saturation current is different for [a] and [b]. Therefore different intensities.
