Question

what are called mechanical waves​

Answer 1

$\huge \red{answer}$

$\huge \underbrace \mathfrak \pink{mechanical \: waves}$

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.
