Q. Penetrating power of $X$-rays can be increased by
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
Explanation
(a) With the increase in potential difference between anode and cathode energy of striking electrons increases which in turn increses the energy (penetration power) of $X$-rays
