Geometric Optics: Snell's Law

Problem #: 1 | Variant #: 4

A light ray hits a surface at an angle of 84o. The material on the other side of the surface has an index of refraction of 1.93 and the light is making an angle of 47.46o with the surface when it exits on this side. What is the index of refraction on the incident side of the interface?
