$\gamma$-rays

Vedclass · Answer

(A) The electromagnetic spectrum is ordered by wavelength. Among the given options,$\gamma$-rays have the highest frequency and therefore the shortest wavelength.Comparing the wavelengths: $\lambda_{\gamma	ext{-rays}} Note that $\alpha$-rays and $\beta$-rays are particle radiations (helium nuclei and electrons,respectively) and do not belong to the electromagnetic spectrum in the same sense as photons; however,in the context of high-energy physics,$\gamma$-rays possess the smallest wavelength among the listed options.

List-$I$	List-$II$
$A.$ Radio-wave	$I.$ Produced by Magnetron valve
$B.$ Micro-wave	$II.$ Due to change in the vibrational modes of atoms
$C.$ Infrared-wave	$III.$ Due to inner shell electrons moving from higher energy level to lower energy level
$D.$ $X$-ray	$IV.$ Due to rapid acceleration of electrons

Which of the following radiations has the least wavelength?
