21Surface 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 …
22Low light level television — LLLTV, or Low Light Level Television, is a type of electronic sensing device, usually a CCD camera with a frequency detection range extending above the normal visible (0.4 to 0.7 micrometre) wavelengths, and into the short wave Infrared usually… …

24Speed of light — The speed of light in the vacuum of free space is an important physical constant usually denoted by the letter c . [NIST and BIPM practice is to use c 0 for the speed of light in vacuum in accord with international standard ISO 31 5. See… …
25Faster-than-light — (also superluminal or FTL) communications and travel refer to the propagation of information or matter faster than the speed of light. Science fiction style space travel, dubbed true FTL, defies known physics.Under the special theory of… …
26Dynamic light scattering — Hypothetical Dynamic light scattering of two samples: Larger particles on the top and smaller particle on the bottom Dynamic light scattering (also known as photon correlation spectroscopy or quasi elastic light scattering) is a technique in… …
27Pp-wave spacetime — In general relativity, the pp wave spacetimes, or pp waves for short, are an important family of exact solutions of Einstein s field equation. These solutions model radiation moving at the speed of light. This radiation may consist of:*… …
28New Wave (science fiction) — New Wave is a term applied to science fiction writing characterized by a high degree of experimentation, both in form and in content, and a highbrow and self consciously literary or artistic sensibility. The term New Wave is borrowed from film… …
29Slow light — is the literal slowing of the speed of light. It is the propagation of an optical pulse or other modulation of an optical carrier at a very low group velocity. The term is usually only applied when the velocity is at least hundreds of times… …
