JEE Main & Advanced Physics Photo Electric Effect, X- Rays & Matter Waves Question Bank X Rays

  • question_answer
    Penetrating power of X-rays can be increased by [MP PMT 1997, 2000]

    A)            Increasing the potential difference between anode and cathode

    B)            Decreasing the potential difference between anode and cathode

    C)            Increasing the cathode filament current

    D)            Decreasing the cathode filament current

    Correct Answer: A

    Solution :

               With the increase in potential difference between anode and cathode energy of striking electrons increases which in turn increases the energy (penetration power) of X-rays.
