Question

What is the correct definition of a compression?

Answer 1

The answer that I found is.....

Compression. A compression is a region in a longitudinal wave where the particles are closest together. Rarefaction. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.

Answer 2

Compression - "Compression is a process in which the actual space covered by any sort of entity is reduced and the values of the given parameters are lowered."

Step-by-step explanation:

Definition with respect to Stress and strain- "The change in actual length,L to a new length,ΔL due to applied stress is called as compression".

Definition with respect to longitudinal wave- "The region of the wave where the particles present are more close to each other is called as compression".
