Webrefraction is also known as Snell's law. The constant in Snell's law is the ratio of the refractive indices of the two materials n and n'. The law of refraction is usually written as sin sin ϕ ϕ′ = n′ n. (1) There are three possible cases; n < n', n = n', and n > n'. When n < n', the light rays pass from a rarified medium like air to a ...

"Web2. Total internal reflection A consequence of Snell’s law is a phenomenon known as total internal reflection. If the ratio of refractive indices n 2/n 1 is less than unity, there will be some ‘critical’ angle of incidence above which the angle of refraction is always greater than 90 degrees. Remembering that the angle of refraction " - Snell's law total internal reflection
