Wave equation — Not to be confused with Wave function. The wave equation is an important second order linear partial differential equation for the description of waves – as they occur in physics – such as sound waves, light waves and water waves. It arises in… … Wikipedia
Wave propagation — is any of the ways in which waves travel through a waveguide.With respect to the direction of the oscillation relative to the propagation direction, we can distinguish between longitudinal wave and transverse waves.For electromagnetic waves,… … Wikipedia
Wave velocity — is a wave property, which may refer to: *phase velocity, the velocity at which a wave phase propagates at a certain frequency *group velocity, the propagation velocity for the envelope of wave groups and often of wave energy, different from the… … Wikipedia
Wave radar — Ocean surface waves can be measured by several radar remote sensing techniques. Several instruments based on a variety of different concepts and techniques are available to the user and these are all often called wave radars. This article (see… … Wikipedia
wave — waveless, adj. wavelessly, adv. wavingly, adv. wavelike, adj. /wayv/, n., v., waved, waving. n. 1. a disturbance on the surface of a liquid body, as the sea or a lake, in the form of a moving ridge or swell. 2. any surging or progressing movement … Universalium
Wave — /wayv/, n. a member of the Waves. Also, WAVE. [1942; see WAVES] * * * I In oceanography, a ridge or swell on the surface of a body of water, normally having a forward motion distinct from the motions of the particles that compose it. Ocean waves… … Universalium
wave motion — ▪ physics propagation of disturbances that is, deviations from a state of rest or equilibrium from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike… … Universalium
dispersive power — noun : the power of a transparent medium to separate different colors of light by refraction as measured by the difference in refractivity for two specified widely differing wavelengths divided by the refractivity at some specified intermediate… … Useful english dictionary
Cnoidal wave — US Army bombers flying over near periodic swell in shallow water, close to the Panama coast (1933). The sharp crests and very flat troughs are characteristic for cnoidal waves. In fluid dynamics, a cnoidal wave is a nonlinear and exact periodic… … Wikipedia
Plane wave expansion method — (PWE) refers to a computational technique in Electromagnetics,solve the Maxwell s equations by formulating an Eigenvalue problem out of it. This method isa popular among Photonic Crystal community, as a method of solving for the band structure… … Wikipedia
Airy wave theory — In fluid dynamics, Airy wave theory (often referred to as linear wave theory) gives a linearised description of the propagation of gravity waves on the surface of a homogeneous fluid layer. The theory assumes that the fluid layer has a uniform… … Wikipedia
