describe with the help of diagram how compression and rarefactions are produced in air near a source of sound
Answers
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.
Compressions are the regions of high pressure (high density of the particles).
Rarefactions are the regions of low pressure (low density of the particles).
When an object starts vibrating it creates disturbance 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.
