Definition of a Refractometer. A refractometer is a versatile and valuable instrument used in various industries to measure the refractive index of a substance. It provides a quick and accurate way to determine the concentration, purity, or quality of a sample by measuring how light bends or refracts as it passes through the sample. .The refractive index n of a medium (e.g., water, olive oil, etc.), also called the index of refraction, is defined as the quotient of the speed of light in vacuum c and the speed of light in the medium v.It is a dimensionless number that depends on the temperature of the medium and the wavelength of the light beam. In simple words, the index of refraction describes how fast a . Index Of Refraction (Refractive Index) Definition. 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.
