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 âthe materialâis limited.Therefore, oscillating material does not move far from its initial equilibrium position.his energy propagates in the same direction as the wave. Any kind of wave (mechanical or electromagnetic) has a certain energy. Mechanical waves can be produced only in media which possess elasticity and inertia. A mechanical wave requires an initial energy input.
Mechanical waves must use matter as a medium, they displace the matter in space. Examples of mechanical waves are sound waves (must go through gas (air) which is matter), ocea â¦ n waves (must go through liquid (water) which is matter, and earthquakes (must go through solid (earth) which is matter. mechanical wave is a wave that needs a medium (type of substance such as gas, liquid or solid) to travel through. Transverse â¦ waves move the medium perpendicular to the energy.
