MCQ
The penetrating power of X-rays increases with the
- AIncrease in its velocity
- ✓Increase in its frequency
- CIncrease in its intensity
- DDecrease in its velocity
✓
Answer
Correct option: B.
Increase in its frequency
$\frac{E}{t}=P=\frac{h v}{t}$i.e. Penetrating power $\propto$ energy $\propto$ Frequency
