en.wikipedia.org/wiki/Mechanical_wave

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 ... Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic ...
