What have to the molecules of a mediumduring (a)a composion and (b) a rare faction?​

Answer»

ANSWER:

Compression and Rarefaction. • Compression- a region in a longitudinal (sound) wave where the particles are closest TOGETHER. • Rarefaction- a region in a longitudinal (sound) wave where the particles are furthest apart.

An EXAMPLE of rarefaction is ALSO as a phase in a sound wave or phonon. Half of a sound wave is made up of the compression of the MEDIUM, and the other half is the decompression or rarefaction of the medium.
