WebAug 2, 2024 · The factor. (9.2.6) n = μ ϵ μ 0 ϵ 0. is called the index of refraction of the material. 1 / n is the ratio of the speed of light in the material to the speed of light in vacuum. In terms of n, we can write (9.52) as. (9.2.7) β y ± = ± n c ε x ±, β x ± = ∓ n c ε y ±. Note also that we can rewrite (9.50) in the following useful form: Web3.5 nD20 refractive index ratio of the velocity of light of a wavelength equivalent to the sodium D line in a vacuum to its velocity in the medium at 20 °C 3.6 production control …
