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.
Matter waves are a central part of the theory of quantum mechanics, being an example of waveâparticle duality. All matter can exhibit wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave. The concept that matter behaves like a wave is also referred to as the de Broglie hypothesis (/dÉËbrÉÉª/) due to having been proposed by Louis de Broglie in 1924. Matter waves are referred to as de Broglie waves.
