Wave Optics

Both reflected and transmitted light are perfectly polarized with angles of reflection and refraction close to $60^{\circ}$ and $30^{\circ}$, respectively

Transmitted light is completely polarized with angle of refraction close to $30^{\circ}$

Reflected light is completely polarized and the angle of reflection is close to $60^{\circ}$

Reflected light is partially polarized and the angle of reflection is close to $30^{\circ}$
