50% of the X-ray coming from a Cooling tube is able to pass through a 0.1 mm thick aluminium foil. The potential difference between the target and the filament is increased. The thickness of aluminium foil, which will allow 50% of the X-ray to pass through, will be

A

zero

B

`lt0.1mm`

C

`0.1mm`

D

`gt0.1mm`

Text Solution

Verified by Experts

The correct Answer is:
B
With increase of potentiaal differece, X-ray of higher energy will be produced , to stop them , thicker foil is required.
