WebOct 12, 2016 · Refractive index (n) is one of the principle defining characteristics of an optical material. In simplified terms, the refractive index defines to what degree light is bent or “refracted” when crossing the boundary between two mediums. It is derived from the relationship between the speed of light in a vacuum, to its speed in the new medium ... WebRefractive index detection is a detection method that applies the principle of light refraction. Fig.2 shows a schematic diagram of a refractive index detector (RID). The light emitted from the lamp passes through the slit and transmits the flow cell as parallel beam. The transmitted light from the flow cell forms a slit image on the photodiode. diary chinese

"In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. The refractive index determines how much the path of light is bent, or refracted, when entering a material. This is described by Snell's … See more The relative refractive index of an optical medium 2 with respect to another reference medium 1 (n21) is given by the ratio of speed of light in medium 1 to that in medium 2. This can be expressed as follows: See more At the atomic scale, an electromagnetic wave's phase velocity is slowed in a material because the electric field creates a disturbance in the charges of each atom (primarily the See more When light passes through a medium, some part of it will always be absorbed. This can be conveniently taken into account by defining a complex refractive index, See more Thomas Young was presumably the person who first used, and invented, the name "index of refraction", in 1807. At the same time he changed this value of refractive power into … See more Refractive index also varies with wavelength of the light as given by Cauchy's equation: The most general form of Cauchy's equation See more The refractive index of materials varies with the wavelength (and frequency) of light. This is called dispersion and causes prisms and rainbows to divide white light into its constituent spectral colors.
