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

(i) When a vibrating object moves forward, it pushes the air in front of it and compresses the air creating a region of high pressure called compression (C).

(ii) It starts moving away from the surface of the vibrating object.

(iii) As this occurs the surface moves backward creating a region of low pressure called rarefaction (R).
