In a previous paper [Appl. Opt. 35, 1566 (1996)] one of us presented new equations for evaluation of the phase refractive index of air over a range of wavelengths and atmospheric parameters. That paper also gave an incorrect, although sufficiently accurate, procedure for calculating the group...

6.2.1 Refractive Index The refractive index, n, of a material is defined as the ratio of the velocity of light in a vacuum relative to the velocity of light passing through that material. The refractive index in a vacuum is defined as 1, and the refractive index of air at 20 °C and...

Learn how to calculate refractive index, discover its applications, delve into the theory, find answers to frequently asked questions, and much more!
The theoretical background and present status of formulas for the refractive index of air are reviewed. In supplement to Edlén's recently revised formula for relative refractivity, the density dependence of refractive index is reanalyzed. New formulas are presented for both phase and group refractive...
14.1.26 REFRACTIVE INDEX Refractive index is measured by a standard method.104 It covers transparent and light colored liquids having a refractive index in the range from 1.33 to 1.50. The refractive index is the ratio of light velocity of a specified wavelength in air to its velocity in the...
