Uncertainties in refractive index, and hence in wave length conversions, due to uncertainties in measured values of temperature, pressure, and humidity exceeds. The air refractive index has a great influence on the wavelength of the interferometer laser. Light slows down when traveling through a medium, thus the index of refraction of any medium. A p w is the vapor pressure of water. Light travels through different media such as air, glass or water at different speeds. Refractive index of a solution depends on the concentration of solute. Metrology institutes have studied this phenomenon and propose a modified edlen formulae 24,25 to calculate it.

Owens} the theoretical background and present status of formulas for the refractive index of air are reviewed. Metrology institutes have studied this phenomenon and propose a modified edlen formulae 24,25 to calculate it.
The sine of the critical angle = refractive index of the refracting medium divided by refractive index of the incident medium.
The index of refraction equals the ratio of the velocities of light in vacuum (c) to that in the medium (v), that is n = c/v.
