[QUOTE="Ibix, post: 6800671, member: 365269"] I think you need the principle that light follows the path that minimises travel time. Then you fix two points and a flat surface, and draw a reflected/refracted ray between the points with the reflection/refraction event lying somewhere on the surface. Write down the travel time, and calculus will then find you the location of the event and you can derive the angles you want from there. [/QUOTE]
