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.
ï± c If the direction of mechanic disturbance (displacement) is parallel to the direction of wave motion, the wave is called longitudinal wave. ï¨see demos. ï± In general, a wave can be a combination of the above modes. ï± The definition can be extended to other (non-mechanical) waves.
