Question

The production of continuous x-ray is due to the
     (A) acceleration of incident electron by the nucleus of the target atom
     (B) electron transitions between inner shells of the target atom
     (C) electron transition between outer shells of the target.
     (D) annihilation of the mass of incident electrons.

Answer 1

Hint:
- We should have a clear understanding of x-ray.
- We should know the structure of atomic nuclei.
- We should know how or electromagnetic radiation is formed due to the collision of energetic electrons with atomic nuclei.

Complete step by step solution:

When high energetic electron beams i.e. cathode rays strike the heavier metal, then x-ray is produced.
Continuous x-ray is produced by the phenomena of i.e. . Bremsstrahlung is electromagnetic radiation produced by the deceleration of a charged particle when deflected by another charged particle typically or electron by an atomic nucleus.

So, option (A) is the correct answer.

Note:
- For detail, we can go through with Einstein equation i.e. \[ev{\text{ }} = {\text{ }}hv\] max.
- The production of continuous x-ray spectrum is the reverse process of competition effect.
