Web25 nov. 2024 · The refractive index is one of the basic concepts in optical sciences. Same as volume, and density, the refractive index is a fundamental property of all materials. However, not only materials that are used in optics have a refractive index. For example, the refractive index of water is 1.33, and the refractive index of air is around to 1.0. WebIt is given by. n 1 sin θ 1 = n 2 sin θ 2. 16.6. When the incident angle equals the critical angle ( θ 1 = θ c ), the angle of refraction is 90° ( θ 2 = 90°). Noting that sin 90° = 1, Snell’s law in this case becomes. n 1 sin θ 1 = n 2. The critical angle, θ c, for a given combination of materials is thus.
