Question

Which of the following is/are true about a mechanical 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. The particles of the medium oscillate when a mechanical wave propagates through it, and the particles are not permanently displaced. i.e. the particles of the medium return to their initial position. So the first three options are correct.
