WebThe refractive index of a substance is dependent on the wavelength λ of the light and the temperature T of the substance. Reference to the refractive index must therefore also specify the wavelength and temperature, if the measurement is not done under standard conditions. The standard wavelength for refractometric measurements is 589 nm. http://sites.und.edu/dexter.perkins/opticalmin/sphene.htm
