Question

What happens to the molecules of a medium during (a) a compression and (b) a rarefaction?​

Answer 1

Answer:

Explanation:

a:Compression happens when molecules are forced, or pressed, together. ... As the molecules are pressed together, they pass the kinetic energy to each other. Thus sound energy travels outward from the source. These molecules are part of a medium, which is anything that carries sound.

b:Rarefaction is just the opposite, it occurs when molecules are given extra space and allowed to expand. ... As the molecules are pressed together, they pass the kinetic energy to each other. Thus sound energy travels outward from the source. These molecules are part of a medium, which is anything that carries sound.
