Light refracted from the Brewster angle
When red light in vacuum is incident at the Brewster's angle on a certain glass slab, the angle of refraction is 32.0 degrees. What are the index of refraction of the glass and the Brewster angle?
If we don't know the Brewster angle, how can we find the index of refraction since you need one to find the other?

The Brewster's angle gives us the following relationship: the incident angle plus the refracted angle equals 90 degrees. You can write this as a simple equation to find the incident angle, then you can use Snell's law to find the the index of refraction of the glass.
