(Some of the incident light is reflected from the surface, but for now we concentrate on the light that is transmitted.) The change in direction of the light ray depends on the relative values of the indices of refraction of the two media involved.

This section describes how rays change direction upon entering a medium according to Snell's Law. Snell's Law is written in terms of the index of refraction of a material is =/, where v is the speed of light in a material and c is the speed of light in a vacuum.
