Question

why sound waves are called mechanical waves? ​

Answer 1

Answer:

Electromagnetic waves do not require a medium in order to transport their energy. Mechanical waves are waves that require a medium in order to transport their energy from one location to another. ... Sound is a mechanical wave and cannot travel through a vacuum.

Answer 2

Answer:

Sound waves are mechanical waves because they need a material medium for propagation, like air or liquids like water, or metals like silver.

Explanation:

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.
