NettetWe define the index of refraction, n, of a material to be n = c v, where v is the observed speed of light in the material. Because the speed of light is always less than c in matter and equals c only in a vacuum, the index of refraction (plural: indices of refraction) is always greater than or equal to one. NettetIt 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°).

NettetThe indices of refraction of the media, labeled , and so on, are used to represent the factor by which a light ray's speed decreases when traveling through a refractive medium, such as glass or water, as opposed to its velocity in a vacuum.

Nettet12. sep. 2024 · The index of refraction for air is taken to be 1 in most cases (and up to four significant figures, it is 1.000). Thus, n1 = 1.00 here. From the given information, θ1 = 30.0° and θ2 = 22.0°. With this information, the only unknown in Snell’s law is n2, so we can use Snell’s law (Equation 1.4.1) to find it.
