Question

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

Answer 1

Hey friend here is your answer.......................

Compression and rarefaction are produced because of the disturbance in medium caused by sound wave. Sound wave propagates because of compression and rarefaction of the particles of the medium.

When an object starts vibrating, it creates disturbance in medium. Because of the disturbance particles of medium come closer to each other compare to their normal position on the other hand adjacent particles go farther to each other. Both happen simultaneously.
