  • question_answer
    In a photoelectric experiment, anode potential is plotted against plate current in figure. Then

    A) A and B will have different intensities while B and C will have different frequencies

    B) B and C will have different intensities while A and C will have different frequencies

    C) A and B will have equal intensities while A and C will have equal frequencies

    D) B and C have equal intensities while A and B will have same frequencies

    Correct Answer: D

    Solution :

    [d] From the graph it is clear that A and B have the same stopping potential and therefore, the same frequency. Also, B and C have the same intensity.
