For harder X- rays - Vidyadip

MCQ

For harder $X-$ rays

A
The wavelength is higher
B
The intensity is higher
✓
The frequency is higher
D
The photon energy is lower

✓

Answer

Correct option: C.

The frequency is higher

c
Hard $x$-rays are the highest energy $x$-rays, while the lower energy $x$-rays are referred to as soft $X$-rays. The distinction between hard and soft $x$-rays is not well defined. Hard x-rays are typically those with energies greater than around $10\,keV$. More relevant to the distinction are the instruments required to observe them and the physical conditions under which the $x$-rays are produced.
