alleryX-rays are produced by bombarding a metal target with:
ALow frequency sound
BHigh energy electrons
CSlow moving neutrons
DOrdinary visible light
Answer & Solution
Correct answer: B. High energy electrons
1. The target must be struck hard enough to disturb inner shells.
2. Charged particles accelerated through a large voltage do it.
3. High energy electrons hit the target.
4. So the answer is high energy electrons.
