MCQ
Penetrating power of $X-$ rays does not depend on
- AWavelength
- BEnergy
- CPotential difference
- ✓Current in the filament
✓
Answer
Correct option: D.
Current in the filament
d
(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.
