The refractive index is a physical property whiclike melting and boiling points, can be used to determine the purity of a compound. It is afunction of the polarizability of compounds, and is very interface of two different media.A beam of light is bent when it passes through the interface of two different media. The lighbeam bends because the velocity changes. The angle of bending or refraction (0.), depends ondensity and temperature of the media, the type of molecules present, and on the wavelength ofthe incident light. If a medium such as air is taken as a standard and the measurements arecarried out at the same temperature and same wavelength of light, the angle measured (as show-below) will be a physical property of the other medium...gLightᎾᎥOrAirSampleThe refractive index (RI) can be determined by computing the ratio of the sine of the angle ofincidence (the angle that incident light makes with an imaginary perpendicular to the intand sine of the angle of refraction (the angle that the light malathe same perpendicular). It can be m
