Index of refraction
|
- The ratio between the angle of incidence to the angle of refraction of light. index varies depending on the density of the medium. the denser the medium, the higher the index.
- The speed of light in a vacuum divided by the speed of light in a material, abbreviated n, which measures how materials refract light.
- The degree to which a lens material refracts (bends) light. this results from the ratio of the speed of light in air to the speed of light through a lens substance; the higher the index of lens material, the quicker light rays are bent as they pass through the lens. the higher the index, the more the refractive power of the lens.
- Коэффициент отражения; показатель преломления
- Ratio of the velocity of light in one medium to its velocity in a second medium as the light passes from medium to medium. if a medium is crystalline, the velocity may depend on the direction of the light with respect to the crystalline axes and the substance may have several indexes of refraction, i.e., it may be birefringent. (also see birefringence.)
- Ratio of velocity of light in a vacuum to velocity of light in a material. see also refractometer.

- The speed of light in a vacuum divided by the speed of light in a material, abbreviated n, which measures how materials refract light.
- A ratio between the velocity of light in air and that of light through a particular substance. the index of air is 1.00 and indices are referred to the index of air, i.e. the index of water being 1.33 means that the spead of light in air is 1.33 times greater as the speed of light in water.
- Index of refraction
- A measure of the magnitude of slowing of light waves by a particular medium
- (astm d-1218) number indicating the angle through which a ray of light is deflected as it passes through a solid or fluid medium; the number that expresses the ratio of the sine of the angle of incidence to the sine of the angle of refraction. typically used for monitoring water-based fluids or solutions.
- Ratio of the speed of the incident wave to that of a refracted wave. it is known as the refractive index of the second medium with respect to the first. glossary 19.17
- Dimensionless ratio of the speed of the incident wave to that of a refracted wave. it helps describe how mechanical or electromagnetic waves change direction as they propagate through dissimilar materials.
- Ratio of the speed of the incident wave to that of a refracted wave. it is known as the refractive index of the second medium with respect to the first.7

Index arbitrage, английский
An investment trading strategy that exploits divergences between actual and theoretical futures prices. an example is the simultaneous buying (selling) of stock index futures (i.e., s&p 500) while selling (buying) the underlying stocks of that index, capturing as profit the temporarily inflated basis between these two baskets. often, the point at which profitability exists is expressed at the block call as the number of points the future must be over or under the underlying basket for an arbitrage opportunity to exist. see: program trading.

Refraction, английский
- The tendency of wave crests to become parallel to bottom contours as waves move into shallower waters. this effect is caused by the shoaling process which slows down waves in shallower waters.
- The change of direction or speed of light as it passes from one medium to another.
- Преломление, рефракция
- Process by which the direction of a radiation is changed as a result of changes in its velocity of propagation.
- The change of direction of propagation of any wave, such as an electromagnetic wave, when it passes from one medium to another in which the wave velocity is different. the bending of incident rays as they pass from one medium to another (e.g., air to glass).
- The change of the propagation direction when a wave comes from one medium into another one
- The directional shift or "bending" of light rays as they leave one density medium and enter a different one. or why your legs are short in water when viewed from the air.
- The bending of light as it passes between materials of different refractive index.
- 1. a change of direction of light rays as they enter a medium such as the eye 2. the measurement of the angle at which the light rays bend, as a test to see if someone needs to wear glasses
- A test to determine the best prescription to correct a refractive error (myopia, hyperopia, astigmatism).
- The change in direction of a light ray or a sound ray in passing from one medium to another. refectory
- Рефракция
- An inflection of the rays of light: that property of the atmosphere which bends the rays of light in their passage to the eye from a different density, and causes the altitude of heavenly bodies to appear greater than it really is, especially near the horizon. (see terrestrial refraction.)
- A wave phenomenon involving change of direction or bending. when a wave of any kind— light, sound, sonar, radar, etc.—passes between materials of different density, its behavior changes as it exits the old medium. and encounters the new one. there is reflection off the boundary and transmission into the new medium. the transmitted wave undergoes refraction when it approaches the boundary obliquely.
- The bending of light as it passes through a diamond or gemstone.
- Bending of light waves, which occurs when a light wave passes from one medium to another
- Change in direction of an acoustic wave as the ultrasonic beam passes from one medium into another having different acoustic speeds. a change in both direction and mode occurs at acute angles of incidence. at small angles of incidence, the original mode and a converted mode may exist simultaneously in the second medium.
- Reorientation of radiation’s path by the medium through which it passes.
- Deflection of a wave due to a change in its speed as it passes from one material to another. see also refractometer.
- Change in direction of an acoustic wave as the ultrasonic beam passes from one medium into another having different acoustic speeds. a change in both direction and mode occurs at acute angles of incidence. at small angles of incidence, the original mode and a converted mode may exist simultaneously in the second medium.7
