Question

On increasing the number of electrons striking the anode of an X-ray tube, which one of the following parameters of the resulting X-rays would increase:-

• A. penetration power
• B. frequency
• C. wavelength
• D. intensity

Answer 1

The correct option is D

intensity

1. Greater the number of electrons striking the anode of an X-ray tube, larger is the number of X-ray photons emitted which means intensity increases.
2. As the penetration power, frequency and wavelength will not increase when electrons striking the anode of an X-ray tube.

Hence the option D is correct.
