In the process of hearing, successive waves of increased density called compression and waves of decreased density called rarefaction cause us to hear
Step-by-step explanation:
Compression occurs when particles are forced, or pressed, together. Rarefaction is the reverse, it befalls when fragments are provided additional space and permitted to expand.
Compression is a spot on a medium within which a longitudinal wave is progressing that has the highest density. A section where the coils are dispersed solely, thus maximizing the space among coils is known as a rarefaction. A rarefaction is a location on a medium within which a longitudinal wave is traveling that has the smallest density.
