Question

Define mechanical wave

Answer 1

Answer :-

Those waves which need a material medium ( like solid, liquid or gas ) for their propagation, are called mechanical waves or elastic waves.

Example - Sound waves, Water waves, Waves produced in spring

Answer 2

Answer:

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.
