Dual Nature Of Light Question 499
Question: Penetrating power of X-rays can be increased by [MP PMT 1997, 2000]
Options:
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
Show Answer
Answer:
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.
