Refractive index of moist air
WebThe index of refraction is defined by n = λ vac /λ air where λ is the wavelength of the radiation. The index is calculated from the expression (n–1) × 108 = 8342.54 + 2406147(130 – σ2)–1 + 15998(38.9 – σ2)–1 where σ = 1/λ vac and λ vac has units of µm. The equation is valid for λ vac from 200 nm to 2 µm. The table also ...
