Surface wave — Diving grebe creates surface waves In physics, a surface wave is a mechanical wave that propagates along the interface between differing media, usually two fluids with different densities. A surface wave can also be an electromagnetic wave guided … Wikipedia
Evanescent wave — Schematic representation of evanescent waves propagating along a metal dielectric interface. The charge density oscillations, when associated with electromagnetic fields, are called surface plasmon polariton waves. The exponential dependence of… … Wikipedia
P-wave — This article is on the type of seismic wave. For the term used in electrocardiography, see P wave (electrocardiography). P wave can also refer to a type of electronic wavefunction in atomic physics; see atomic orbital. Plane P wave … Wikipedia
Standing wave ratio — In telecommunications, standing wave ratio (SWR) is the ratio of the amplitude of a partial standing wave at an antinode (maximum) to the amplitude at an adjacent node (minimum), in an electrical transmission line. The SWR is usually defined as a … Wikipedia
Alpha wave — Alpha waves are electromagnetic oscillations in the frequency range of 8–12 Hz arising from synchronous and coherent ( in phase / constructive ) electrical activity of thalamic pacemaker cells in the human brain. They are also called Berger s… … Wikipedia
