Expert Answer:

Rarefactions:- 
 
A sound wave can be considered the propagation of pressure or density variations in the medium, i.e. it propagates in a medium as a series of compressions and rarefactions.
A vibrating object produces a series of compressions and rarefactions in the medium.
A region of compressed air (increased density or pressure) is called a compression (C) and that of rarefied air (decreased density or pressure) is called a rarefaction (R).
