because
Statement-2
When an electron beam strikes the target in an X-ray tube, part of the kinetic energy is converted into X-ray energy.

A

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1

B

Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement -1

C

Statement-1 is True, Statement-2 is Flase

D

Statement -1 is False, Statement-2 is True

Text Solution

Verified by Experts

The correct Answer is:
B
Both statements are correct but statement `(2)` is not correct explaination of statement `(1)` Energy of characterstics x-ray depends on the different in energy levels.
