  • question_answer
    If photoelectric  effect experiment, the intensity of incident ray increases, then the correct statement is

    A)  the kinetic energy of emitted electron will be maximum

    B)  work function will be unchanged

    C)  stopping potential will be increases

    D)  the kinetic energy of emitted electron will be become less

    Correct Answer: B

    Solution :

     With the increase in intensity of hght photoelectric current increases, but kinetic energy of ejected electrons, stopping potential and work function remain unchanged.
