The waves emitted when a metal target is bombarded with high energy electrons are
Options
- AMicrowaves
- BInfrared rays
- CX-rays
- DRadio Waves
Correct answer
C. X-rays
Step-by-step solution
The bombarding electrons can eject electrons from the inner shells of the atoms of the metal target. Those vacancies will be quickly filled by electrons dropping from higher levels, emitting x-rays with sharply defined frequencies associated with the difference between the atomic energy levels of the target atoms. Hence, X-rays are emitted when a metal target is bombarded with high energy electrons.
