Rarefaction
Explanation:
A place where molecules are far apart is a Rarefaction.
Rarefaction is the opposite of compression. Rarefaction is the reduction of an item's density. Rarefaction waves exist in nature also. Rarefaction is a part of sound waves. Half of the sound wave is the decompression of the medium.
It is caused as a result of the change in the speed of light as it enters from one medium to another.
A rarefaction is a place in a longitudinal wave where the molecules are far apart.
