MCQ
Penetrating power of $X$-rays does not depend on
  • A
    Wavelength
  • B
    Energy
  • C
    Potential difference
  • Current in the filament

Answer

Correct option: D.
Current in the filament
When current through the filament increases, number of emitted electrons also increases. Hence intensity of $X$-ray increases but no effect on penetration power.
