** Dispersion ( optics ), for light waves

** Dispersion relation, the mathematical description of dispersion in a system

** Dispersion of the apostles

** Water jet ( personal water craft, jetboat )

** Ecosystems: biodiversity — biome — habitat — plankton — thermocline — carbon cycle — water cycle — nitrogen cycle — food web — trophic level — saprobe — decomposition

** Powdered milk ( or milk powder ), produced by removing the water from ( usually skim ) milk

** Pier, a raised walkway over water, supported by widely spread piles or pillars

** Brownian dynamics, the occurrence of Langevin dynamics in the motion of particles in solution ( e. g. a grain in water, as was first seen by Brown ); its famous property is: MSD ~ t, where MSD is the mean squared displacement, and t is the time the process is seen

** Water ( hydroelectric )-Turbine blades are acted upon by flowing water, produced by hydroelectric dams or tidal forces.

** water: 200 km²

** Hemlock water dropwort ( Oenanthe crocata )

** Chamois leather also falls into the category of aldehyde tanning and like brain tanning produces a highly water absorbent leather.

** Naiads or Naides ( fresh water )

** Oceanids ( daughters of Oceanus and Tethys, any water, usually salty )

** Advanced Heavy Water Reactor ( AHWR )— A proposed heavy water moderated nuclear power reactor that will be the next generation design of the PHWR type.

** Salt ( sodium ) and water retention

** water: 7, 160 km²

** Exostosis is an abnormal bony overgrowth narrowing the ear canal due to frequent, long-term splashing or filling of cold water into the ear canal, also known as surfer's ear.

** Oxygen in water.

** Carbon dioxide in water is a less simple example, because the solution is accompanied by a chemical reaction ( formation of ions ).

** Alcoholic beverages are basically solutions of ethanol in water.

** Sucrose ( table sugar ) in water

** Sodium chloride ( table salt ) or any other salt in water forms an electrolyte: When dissolving, salt dissociates into ions.

** a smaller limnetic species — with a smaller mouth — that feeds on the small plankton in open water

** The terrestrial region, according to Aristotle, consisted of concentric spheres of the four elements — earth, water, air, and fire.

** water sprites, such as the Neck ( water spirit )

** Acoustic dispersion, for sound waves

** Optical medium, material through which electromagnetic waves propagate

** Project Diana bounces radar waves off the Moon, measuring the exact distance between the Earth and the Moon, and proving that communication is possible between Earth and outer space, effectively opening the space age.

** In Irian Jaya, an earthquake of magnitude 7. 5 and associated tidal waves kills 102 people and causes widespread devastation.

** The Draupner wave in the North Sea in Norway is detected, confirming the existence of rogue waves.

** A hurricane and huge waves kill about 2, 500 in Santa Cruz del Sur in the worst natural disaster in Cuban history.

** Energy loss in a shock wave, normal and oblique shock waves

** Antenna – converts propagating electromagnetic waves to and from conducted electrical signals

** Submillimeter waves are used in physics to study materials in high magnetic fields, since at high fields ( over about 11 tesla ), the electron spin Larmor frequencies are in the submillimeter band.

** The " training pool " is located in the basement and is 16 m by 50 m in size, with a constant depth of 1. 8 m. A traversable boom allows separation into two 25 m length pools, one of which can be varied in depth from floor level to 1. 8 m. The training pool's ceiling is in the shape of two long waves representing waves on water.

** Airy wave theory, a linear theory describing the propagation of " gravity waves " on the surface of a fluid

** 1st round: 1 – 2 meters ( 4 – 6 foot ) waves with cross winds

** 2nd round: 1 – 2 meters ( 4 – 6 foot ) thundering tubular waves with offshore winds

** 2nd round: Small 1-1, 5 meters ( 4 – 6 foot ) waves

** study and report on existing natural energy resources including wind, solar, waves and tides ;

** Sonic Screamer: A long range weapon that fires ultra-high frequency sound waves.
