Webb5 juli 2024 · Snell's Law. Snell's law relates the sines of the angles of incidence and transmission to the index of refraction for each material: (3) sin θ 1 sin θ 2 = n 2 n 1. It should be noted that the angles are measured from the normal line at the interface (Figure 1). Figure 1: Refraction at the interface between two materials (Wikipedia) WebbThe latter has a refractive index which is generally not the extraordinary index n e, but a rather a mixture of n e and n o. This can be calculated with the following equation: The equation shows that for θ → 0 (i.e., …
