body mass index (BMI) the weight in kilograms divided by the square of the height in meters, a measure of body fat that gives an indication of nutritional status. cardiac index cardiac output corrected for body size. cephalic index 100 times the maximum breadth of the skull divided by its maximum length. refractive index. (General Physics) physics a measure of the extent to which radiation is refracted on passing through the interface between two media. It is the ratio of the sine of the angle of incidence to the sine of the angle of refraction, which can be shown to be equal to the ratio of the phase speed in the first medium to that in the second. Refractive index is the ratio of the velocity of light of a specified wavelength in the air to its velocity in the examined substance. When this principle of measurement is used it may be defined as the sine of the angle of incidence divided by the sine of the angle of refraction. The index of refraction for a given medium is a unitless number n where n = c/v, where c is the speed of light in a vacuum and v is the speed of light in the medium. The slower light travels in a medium, the higher that medium's index of refraction will be. Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. If i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction Refractive index database [about] Shelf MAIN - simple inorganic materials ORGANIC - organic materials GLASS - glasses OTHER - miscellaneous materials 3D - selected data for 3D artists In optics, the refractive index or index of refraction of a material is a dimensionless number that describes how fast light travels through the material. It is defined as =, where c is the speed of light in vacuum and v is the phase velocity of light in the medium. For example, the refractive index of water is 1.333, meaning that light travels 1/1.333 times as fast in vacuum as in water.

Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers. There are also weaker dependencies on temperature , pressure / stress , etc., as well on precise material compositions (presence of dopants , etc.); for many materials and typical conditions, however, these variations are at the percent level or less.
Birefringence is the difference between the two indices of refraction. Strong and weak birefringence look as follows for uniaxial minerals: The Becke lines are an The refractive index is required in order to perform the theoretical light scattering predictions that are used for instrument calibrations. One purpose of this work was Measurement of refractive indices of solid. Chart1 : Examples of measurements and the methods. Material characteristics, Measuring materials, Measuring method.

Refractive Index (Index of Refraction) Refractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by the letter n or n' in descriptive text and mathematical equations. Refractive index is the measurement of that angle: the ratio of the velocity of light in the air to the velocity of light in a medium through which it passes. Knowing a refractive index can help you (a) identify the medium in a liquid or (b) measure the purity and concentration of a medium in that liquid. The index of refraction, or refractive index, is a measure of how fast light rays travel through a given medium. Alternatively, it could be said that refractive index is the measure of the bending of a light ray when passing from one medium to another. The refractive index is a function of the wavelength.The most common characteristic quantity for characterization of an optical glass is the refractive index n in the middle range of the visible spectrum. This principal refractive index is usually denoted as n d – the refractive index at the wavelength 587.56 nm or in many cases as n
The refractive index (or index of refraction) of a medium is a measure for how much the speed of light (or other waves such as sound waves) is reduced inside the medium. For example, typical soda-lime glass has a refractive index of 1.5, which means that in glass, light travels at $ 1/1.5=0.67 $ times the speed The refractive indices which were measured along the dashed line in Figure 1(c) at the radius of 0, 25 mm, 50 mm, 65 mm, 75 mm and plotted in Figure 4 demonstrate that the refractive indices of the film are also approximately consistent with the minority carrier lifetime, the same as the situation discussed previously. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers. There are also weaker dependencies on temperature , pressure / stress , etc., as well on precise material compositions (presence of dopants , etc.); for many materials and typical conditions, however, these variations are at the percent level or less. Refractive index is the ratio of the velocity of light of a specified wavelength in the air to its velocity in the examined substance. When this principle of measurement is used it may be defined as the sine of the angle of incidence divided by the sine of the angle of refraction.
