Assertion : Anode of Coolidge tube gets ...

Assertion : Anode of Coolidge tube gets heated up at time of emission of `X` - rays .
Reason : The anode of Coolidge tube is made of a material of high melting point.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
B
When fast moving electrons strike the atoms of the target , then most of their kinetic energy is used in target and only a small part is radiated in the form of `X` - rays . So the temperature of the target rises.
