While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.]]> 2017-11-14 20:21:39 UTC https://padlet.com/3049391/svjc47eabx22/wish/206954392 3049391 https://padlet.com/3049391/svjc47eabx22/wish/206958281

an oscillation of the parts of a fluid or an elastic solid whose equilibrium has been disturbed, or of an electromagnetic wave.
