Question

What is a sound wave?

• A. A disturbance that propagates through the medium
• B. An oscillation that propagates through the medium
• C. It is accompanied by energy transfer
• D. All of these

Answer 1

Answer: (A), (B), (C)

The correct options are
A

A disturbance that propagates through the medium

B

An oscillation that propagates through the medium

C

It is accompanied by energy transfer

Wave is a disturbance that propagates in a medium and transfers energy and momentum without permanent displacement of particles of the medium. To and fro motion of the particles results in oscillations. So the first three options are correct.
