Define: 1. Compression 2. Rarefaction

Text Solution

Verified by Experts

1. Compression: A region of high pressure and high density formed in a medium as a longitudinal wave passes through it is called a compression
2. Rarefaction: A region of low pressure and low density formed in a medium as a longitudinal wave passes through it is called rarefaction.
