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.
Longitudinal waves, also known as compression waves when describing waves in mechanical terms, are waves where the vibration is parallel to the direction the wave is moving. That might be hard to picture, which is why we need some help from a Slinky.
