Question

Sound waves are:

• A. Mechanical waves.
• B. Non-mechanical waves.
• C. Zero-energy waves.
• D. Electromagnetic waves.

Answer 1

The correct option is A

Mechanical waves.

Mechanical waves are the waves that need a medium to propagate and during their propagation, there is no actual displacement of the particles of the medium. Sound also needs a medium to travel. Hence it is a mechanical wave.
