Answer 2

An area with a high density of particles is called Compression.

• If the density of air molecules is extra in the provided region, then the number of air molecules is close to each other. Such a region in a sound wave or more commonly a longitudinal wave is known as compression and encompasses a region of high pressure.
• Compression is a region of the medium in which particles reach closer, that is the distance between the particles comes to be less than the ordinary distance between them. Therefore there is a temporary decrease in volume and a resultant increase in the density of the medium.
• Likewise, in rarefaction, particles get distant apart and a resultant decrease in density. Thus, Compression is a region in a longitudinal wave where the particles are nearest together.
