Snell's law of refraction
The incident ray, the normal to the refracting surface at the point of incidence of the ray at the surface, and the refracted ray all lie in a single plane. The ratio of the sine of the angle between the normal and the incident ray to the sine of the angle between the normal and refracted ray is a constant. If the indices of refraction on either side of a refracting surface are N and N', and the angles that a ray makes with the surface normal are i and r, then Snell's law states that N...
