the refractive index is measured
11Electromagnetically induced transparency — The effect of EIT on a typical absorption line. A weak probe normally experiences absorption shown in blue. A second coupling beam induces EIT and creates a window in the absorption region (red). This plot is a computer simulation of EIT in an… …
12Electro-gyration — The electrogyration effect is the spatial dispersion phenomenon, that consists in the change of optical activity (gyration) of crystals by a constant or time varying electric field. Being a spatial dispersion effect, the induced optical activity… …
13Mikheyev–Smirnov–Wolfenstein effect — The Mikheyev–Smirnov–Wolfenstein effect (often referred to as matter effect) is a particle physics process which can act to modify neutrino oscillations in matter. 1978 work by American physicist Lincoln Wolfenstein and 1986 work by Soviet… …
14Oechsle scale — The Oechsle Scale is a hydrometer scale measuring the density of grape must[1], which is an indication of grape ripeness and sugar content used in wine making. It is named for Ferdinand Oechsle (1774 1852) and it is widely used in the German,… …
15Microwave transmission — The atmospheric attenuation of microwaves in dry air with a precipitable water vapor level of 0.001 mm. The downward spikes in the graph correspond to frequencies at which microwaves are absorbed more strongly, such as by oxygen molecules… …
16Fizeau experiment — The Fizeau experiment was carried out by Hippolyte Fizeau in the 1851 to measure the relative speeds of light in moving water. Albert Einstein later pointed out the importance of the experiment for special relativity.The experimentFizeau s test… …
17optics — /op tiks/, n. (used with a sing. v.) the branch of physical science that deals with the properties and phenomena of both visible and invisible light and with vision. [1605 15; < ML optica < Gk optiká, n. use of neut. pl. of OPTIKÓS; see OPTIC,… …
18Brix — For other uses, see Brix (disambiguation). Degrees Brix (symbol °Bx) is the sugar content of an aqueous solution. One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by weight (% …
19industrial glass — Introduction solid material that is normally lustrous and transparent in appearance and that shows great durability under exposure to the natural elements. These three properties lustre, transparency, and durability make glass a favoured… …
20Birefringence — Displacement of light rays with perpendicular polarization through a birefringent material …
