## Homework Statement

Consider a beam of unpolarised light incident onto air from a crown-glass with a refractive index of 1.52.

Determine the incident angle when the reflected light becomes completely polarised. What is the polarised state of the reflected light?

## Homework Equations

Brewster's Law: n=tan(theta)

## The Attempt at a Solution

I did get 56.7 degrees so that's the incident angle. But from the angle, how do I determine the polarised state?

(One of these right? Linear, Circular and Elliptical)
