**wave**— 1. A formation of forces, landing ships, craft, amphibious vehicles or aircraft, required to beach or land about the same time. Can be classified as to type, function or order as shown: a. assault wave; b. boat wave; c. helicopter wave; d.… …33

**Wave front set**— In mathematical analysis, more precisely in microlocal analysis, the wave front (set) WF( f ) characterizes the singularities of a generalized function f , not only in space, but more precisely also with respect to its Fourier transform at each… …34

**Wave of Long Island**— The Wave of Long Island is the longest lived and most widely circulated newspaper in the Rockaway Peninsula, New York City Borough of Queens. The weekly paper, currently under the editorship of Howard Schwach, is well known to Rockaway residents… …35

**wave velocity**— ▪ physics distance traversed by a periodic, or cyclic, motion per unit time (in any direction). Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. The velocity of a wave is equal to the… …36

**wave cyclone**— A cyclone that forms and moves along a front. The circulation about a wave cyclone tends to produce a wavelike deformation of the front. Direction of motion of center …37

**wave·length**— /ˈweıvˌlɛŋkθ/ noun, pl lengths [count] 1 technical : the distance from one wave of energy to another as it is traveling from one point to another point Light and sound have different wavelengths. radio wavelengths 2 informal used especially in… …38

**Spin wave**— Spin waves are propagating disturbances in the ordering of magnetic materials. These low lying collective excitations occur in magnetic lattices with continuous symmetry. From the equivalent quasiparticle point of view, spin waves are known as… …39

**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… …40

**Heat wave**— A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity. There is no universal definition of a heat wave;cite journal |last=Meehl |first=George A. |coauthors=Tebaldi, Claudia |title=More Intense,… …
