Question

If voltage of X-ray tube is doubled then intensity of X-rays will :-

• A. halved
• B. remains constant
• C. doubled
• D. quadrupled

Answer 1

The correct option is B

remains constant

1. If the voltage of X-rays tube is double, the intensity of X-ray will be unchanged
2. As the intensity of the X-ray beam depends on the number of electrons striking the target per second and not on voltage.

Hence, option (B) is correct.
