Question

What is the point where the density of the vibrating air molecules is maximum and its rear fraction is minimum​

Answer 1

Answer:

The point where the refraction of the vibrating air molecules is minimum and its density is maximum is called a crest.

Answer 2

Explanation:

The point where the refraction of the vibrating air molecules is minimum and its density is maximum is called a crest

define crest-A crest is the point on a wave with the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
