Acoustic Wave: (acoustics) a wave that transmits sound.

Refraction: the change in direction of a propagating wave (light or sound) when passing from one medium to another.

Reflection: the phenomenon of a propagating wave (light or sound) being thrown back from a surface.

Acoustic Radiation Pressure: (acoustics) the pressure exerted on a surface normal to the direction of propagation of a sound wave.

Billow: a large sea wave.

Heat Wave: a wave of unusually hot weather.

Beckon: summon with a wave, nod, or some other gesture.

Crest: the top line of a hill, mountain, or wave.

Riffle: a small wave on the surface of a liquid.

Cold Wave: a wave of unusually cold weather.

Spectrum: an ordered array of the components of an emission or wave.

Backwash: the wave that spreads behind a boat as it moves forward.

Hertzian Wave: an electromagnetic wave generated by oscillations in an electric circuit.

White Horse: a wave that is blown by the wind so its crest is broken and appears white.

Tsunami: a cataclysm resulting from a destructive sea wave caused by an earthquake or volcanic eruption.

Tidal Wave: a wave resulting from the periodic flow of the tides that is caused by the gravitational attraction of the moon and sun.

Aegir: a high wave (often dangerous) caused by tidal flow (as by colliding tidal currents or in a narrow estuary).
