- This article is about waves in the most general scientific sense; a separate article focuses on ocean waves.
- For other meanings see wave (disambiguation).
A wave is a disturbance that propagates through space, often transferring energy. While a mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces), waves of electromagnetic radiation (and probably gravitational radiation) can travel through vacuum, that is, without a medium. Waves travel and transfer energy from one point to another, with little or no permanent displacement of the particles of the medium (there is little or no associated mass transport); instead there are oscillations around fixed positions.

I really just wanna be on a beach laying in the sand and listening to the waves crash...
