Rotating wave approximation — The rotating wave approximation is an approximation used in atom optics and magnetic resonance. In this approximation, terms in a Hamiltonian which oscillate rapidly are neglected. This is a valid approximation when the applied electromagnetic… … Wikipedia
Wave — A wave is a disturbance that propagates through space and time, usually with transference of energy. While a mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces), waves of electromagnetic… … Wikipedia
Wave (audience) — Stadium crowd performing the wave at the Confederations Cup 2005 in Frankfurt The wave (North American) or the Mexican wave (outside North America) is an example of metachronal rhythm achieved in a packed stadium when successive groups of… … Wikipedia
Wave swinger — The Wave Swinger premiered in Germany in 1972 as a park model designed by Zierer and built by Franz Schwartzkopf. In 1974 the first portable Wellenflug (as it is known in its home country of Germany) debuted under the same partnership. Since this … Wikipedia
Wave Swinger — The Wave Swinger is an amusement ride, often called a swing or swinger ride, like a Yo Yo or Chair o Planes. However the Wave Swinger s unique design separates it from most other swing rides, as the canopy from which the swings are hung tilts and … Wikipedia
Inertial wave — Inertial waves, also known as inertial oscillations, are a type of mechanical wave possible in rotating fluids. Unlike surface gravity waves commonly seen at the beach or in the bathtub, inertial waves travel through the bulk of the fluid, not at … Wikipedia
Gravitational wave — In physics, a gravitational wave is a fluctuation in the curvature of spacetime which propagates as a wave, traveling outward from a moving object or system of objects. Gravitational radiation is the energy transported by these waves. Important… … Wikipedia
Audience wave — The wave ( British English: Mexican wave ; also stadium wave), is achieved in a packed stadium when successive groups of spectators briefly stand and raise their arms. Each spectator is required to rise at the same time as those straight in front … Wikipedia
Density wave theory — Image of spiral galaxy M81 combining data from the Hubble, Spitzer, and GALEX space telescopes. Density wave theory or the Lin Shu density wave theory is a theory proposed by C.C. Lin and Frank Shu in the mid 1960s to explain spiral arm structure … Wikipedia
Rossby wave — Rossby (or planetary) waves are giant meanders in high altitude winds that are a major influence on weather. Their emergence is due to shear in rotating fluids, so that the Coriolis force changes along the sheared coordinate. In planetary… … Wikipedia
Gravitational wave astronomy — is an emerging branch of observational astronomy which aims to use gravitational waves (minute distortions of spacetime predicted by Einstein s theory of general relativity) to collect observational data about objects such as neutron stars and… … Wikipedia
