Question

define mechanical waves ​

Answer 1

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.

Answer 2

Answer:

Mechanical waves :- Waves which require medium for propagation of sound is termed as mechanical waves. They are also called as known waves because their propagation depends upon the elastic properties of the medium through the waves are travelling.

Example of Mechanical waves :-

• Waves that are produce during earth quake. These is also known as seismic waves.
• Waves over the surface of water.
• Sound waves that are produce in air
