Question

X-rays are ______________ of wavelength ~ 1 A˚ (10^-10m).

(a) Rays from visible region

(b) Rays from proton

(c) Electromagnetic radiation

(d) Electric radiation

This question was addressed to me in an online interview.

The query is from X-rays and their Generations topic in chapter X-Ray Diffraction of Solid State Chemistry

Answer 1

Correct choice is (c) Electromagnetic radiation

To explain I would say: X-rats are electromagnetic radiation. They occur in that part of the electromagnetic spectrum between ϒ-rays and the ultraviolet. X-rays are produced when high energy charged particles e.g. electrons accelerated through high voltage.
