A '''wave''' is a disturbance that propagates through [[spacetime|space and time]], usually with transference of [[energy]]. A [[mechanical]] wave is a wave that propagates or travels through a [[medium]] due to the restoring [[force]]s it produces upon deformation. There also exist waves capable of traveling through a [[vacuum]], including electromagnetic radiation and probably[1] gravitational radiation. Waves travel and transfer energy from one point to another, often with no permanent displacement of the particles of the medium (that is, with little or no associated [[mass]] transport); they consist instead of oscillations or vibrations around almost fixed locations. | A '''wave''' is a disturbance that propagates through [[spacetime|space and time]], usually with transference of [[energy]].
