MCQ

The characteristic $X-$ ray radiation is emitted, when

A
The electrons are accelerated to a fixed energy
B
The source of electrons emits a monoenergetic beam
✓
The bombarding electrons knock out electrons from the inner shell of the target atoms and one of the outer electrons falls into this vacancy
D
The valence electrons in the target atoms are removed as a result of the collision

✓

Answer

Correct option: C.

The bombarding electrons knock out electrons from the inner shell of the target atoms and one of the outer electrons falls into this vacancy
