What determines the hardness of the `X` - rays obtained from the Coolidge filament ?

A

Current in the filament

B

Pressure of air in the tube

C

Nature of target

D

Potential difference between cathode and target

Text Solution

Verified by Experts

The correct Answer is:
D
Hard `X `- rays are of higher energy and the energy of `X` - rays depends on the potential difference between the cathode and the target.
