MCQ

The essential distinction between $X-$ rays and $\gamma - $ rays is that

A
$\gamma - $ rays have smaller wavelength than $X-$ rays
✓
$\gamma - $ rays emanate from nucleus while $X-$ rays emanate from outer part of the atom
C
$\gamma - $ rays have greater ionizing power than $X-$ rays
D
$\gamma - $ rays are more penetrating than $X-$ rays

✓

Answer

Correct option: B.

$\gamma - $ rays emanate from nucleus while $X-$ rays emanate from outer part of the atom

b
(b)The wavelength of the $X$-rays is shorter. However the main distinguishing feature is the nature of emission.
