  1. Snell’s Law n1sinθ1=n2sinθ2 n1: index of refraction of medium 1 n2: index of refraction of medium 2 θ1: the angle of light in medium 1 θ2: the angle of light in medium 2 Light bends towards the normal when going from a medium with a smaller index of refraction to a larger index of refraction. (Light will have the smaller angle in the medium with the greater index of refraction.) θ1 A relationship relating the index of refraction in a given a medium and incident light angle to the index of refraction in the new medium and the refracted light angle. n1 n2 θ2
