A laser enters a transparent medium from air at 45 degrees from the surface normal. The beam is transmitted through the medium at 30 degrees from the normal. Assuming the refractive index of air to be 1, and remembering that Snell's Law says that N-1 Sine-1 equals N-2 Sine-2, for ten points, calculate the refractive index of the unknown medium.
