$\red{\bold{\underline{\underline{Compression:-}}}}$

➥Air is the most common medium through which sound travels .When a vibrating object moves forwards , it pushes and compresses the air in front of it creating a region of high pressure.This region is called compression.

$\pink{\bold{\underline{\underline{Rarefaction:-}}}}$

➥When the vibrating object moves forwards it creates a region of low pressure called rarefaction. Thus rarefaction is the region of low pressure and decrease density.

➥Hence, a series of compression and rarefaction is created in the air make the sound waves propogate through the medium.
