Q. Penetrating power of $X$-rays does not depend on
A) Wavelength
B) Energy
C) Potential difference
D) Current in the filament
Explanation
(d) When current through the filament increases, number of emitted electrons also increases. Hence intensity of $X$-ray increases but no effect on penetration power
