The refractive index and the specific refractive index increment can be predicted via additive molar properties. List of refractive indices ( = 589 nm) www.vaxasoftware.comSolids Name Formula Temperature °C ( )n Agate SiO2 25 1.53-1.54 Aluminium oxide Al2O3 25 1.76 Aluminium phosphate AlPO4 25 1.53 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 range can be measured, i.e., the critical angle is always within this selection. The measuring prism acts as the refractive index reference. The refractive index of the prism has to be higher than that of the medium under measurement, as otherwise there will be no total internal reflection. Filmetrics ® systems measure refractive index and extinction coefficient over wavelengths as wide as 190-1700 nm - in seconds and with a single mouse-click.

Absolute Refractive Index. As mentioned before, to calculate the refractive index, two different mediums are considered. But, when one of the two mediums is considered a vacuum, then the refractive index of the second medium, concerning the first medium, is known as Absolute Refractive Index. The symbol n₂ denotes the absolute Refractive Index. The refractive index of a medium is defined as how the light travels through that medium.It is a dimensionless measure. It defines how much a light ray can be bent when it enters from one medium to the other. 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 book is concerned with properties such as density, refractive index, acoustic impedance and electrical conductivities of hydrocarbon substances.

It is commonly used to identify a particular substance, determine its purity, or measure concentration. For example, it is used in the sugar processing industry to determine the mass Refractive Index Formula: The value of this constant, \(\frac{\sin \,i}{\sin \,r}\) for a light ray passing through a vacuum into a given medium is called the refractive index, n of the medium. It is defined as: This relationship is also known as Snell’s law. (a) Refractive Index in terms of Speed of Light: OELCHECK measures refractive indices using the RX40 Refractive Index Cell Module from Mettler Toledo. This produces the wavelengths of light required with high accuracy, and determines refractive indices within a value range of 1.3200 to 1.7000. The refractive index can then be used to determine the mixing ratio of two components.

The refractive index of hetero-polymers (blends, copolymers, composites, and semi-crystalline polymers) with similar constituent refractive indices can be predicted by a simple additivity approach. The refractive index and the specific refractive index increment can be predicted via additive molar properties.
