A Wave Carries Energy, Not Water
A wave is a moving ridge on water or a hand gesture. What travels is energy, not the medium.
A wave is a moving ridge on the surface of water, or a movement of the hand. An ocean wave does not carry water across the sea: each particle moves in a small circle and returns roughly to where it started, while the energy travels onward. A floating gull rises and falls without being carried to shore, which is the clearest demonstration. *Wave* is Old English *wafian*, to move the hands, and the water sense was influenced by the older word *wæg*, a wave.
- A water ridge. *A breaking wave.*
- A hand gesture. *A wave goodbye.*
- A surge. *A wave of protest.*
- Wavelength. *A wavelength.*
- Old English — *wafian*. *The source.*

What actually moves in a wave
- Water particles move in small circles and return near their start
- The energy travels forward through the medium
- A floating object bobs rather than being carried along
- Only when a wave breaks does water genuinely move forward
- Sound and light carry energy through media the same way
Old English *wafian*, to move the hands, influenced by *wæg*, a wave or motion.
Does a wave carry water across the ocean?
No. Water particles move in small circles and return nearly to their start; only the energy travels onward.
Why does a gull not get carried to shore?
Because it rises and falls with the passing energy rather than being transported by moving water.
