Radio waves

Vedclass · Answer

(A) The electromagnetic spectrum consists of radio waves,microwaves,infrared,visible light,ultraviolet,$X$-rays,and gamma rays in increasing order of frequency.Radio waves have the lowest frequency among electromagnetic waves.Sound waves and ultrasonic waves are mechanical waves,not electromagnetic waves.Sound waves typically have frequencies in the range of $20 \ Hz$ to $20,000 \ Hz$,while ultrasonic waves have frequencies above $20,000 \ Hz$.Radio waves have frequencies starting from approximately $3 \ kHz$ $(3 	imes 10^3 \ Hz)$.Comparing the given options,radio waves have the lowest frequency among the electromagnetic spectrum components listed,but sound waves (audible range) have even lower frequencies than radio waves.However,in the context of standard physics questions regarding the electromagnetic spectrum,radio waves are the correct answer for the minimum frequency among the listed electromagnetic waves.

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
