Brewster's Angle Calculator

Calculate the Brewster angle at which reflected light is fully polarized from the refractive indices of two media

Frequently Asked Questions

What happens to light at the Brewster angle?

At the Brewster angle the reflected light is completely polarized parallel to the surface, which is why polarized sunglasses cut glare so effectively.

What is the Brewster angle for glass?

For light passing from air into glass with a refractive index near 1.5, the Brewster angle is about 56 degrees from the normal.
