Describe with the help of a diagram, how compressions and rarefactions are produced in the air near a source of sound.​

Answer 1

$\huge\mathcal{\fcolorbox{lime}{black}{\pink{Answer}}}$

--> Compressions and rarefactions are produced because of the disturbance in medium caused by sound wave.

-->Sound waves propagate because of compressions and rarefactions of the particles of the medium.

ㅤㅤ‎ㅤㅤㅤㅤ◍ Describe with the help of a diagram, how compressions and rarefactions are produced in the air near a source of sound.

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\blue{W}\green{E}\pink{R}}}}$⤵

☞︎︎︎Compressions and rarefactions are produced because of the disturbance in medium caused by sound wave.

☞︎︎︎Sound waves propagate because of compressions and rarefactions of the particles of the medium.

☞︎︎︎Compressions are the regions of high pressure (high density of the particles).

☞︎︎︎ Rarefactions are the regions of low pressure ㅤㅤ(low density of the particles).

☞︎︎︎ When an object starts vibrating it creates ㅤㅤ‎ ㅤdisturbance in the medium.

☞︎︎︎ Because of the disturbance of the particles of medium, they come closer to each other as compare to their normal position.

☞︎︎︎ On the other hand adjacent particles go farther to each other. Both happen simultaneously.

☞︎︎︎ The region where particles come closer to each other is called compressions and region where particles go farther from each other are called rarefactions.
