Microwaves

Vedclass · Answer

(D) Communication systems,such as satellite communication,radar,and mobile networks,primarily utilize electromagnetic waves in the radio and microwave frequency ranges.$X-rays$ and $\gamma$ rays have very high frequencies and energies,making them unsuitable for long-distance communication due to their ionizing nature and difficulty in modulation.Sound waves are mechanical waves and require a medium to travel,making them impractical for long-distance wireless communication.Microwaves,which fall within the radio frequency spectrum,are widely used for point-to-point communication,satellite links,and wireless networks due to their ability to carry large amounts of information and their propagation characteristics.Therefore,the correct option is $D$.

List-$I$	List-$II$
$A$. Microwaves	$I$. Physiotherapy
$B$. $UV$ rays	$II$. Treatment of cancer
$C$. Infra-red rays	$III$. Lasik eye surgery
$D$. $X$-rays	$IV$. Aircraft navigation
