Brewster Angle Calculator — Formel
## Brewster's Angle
At Brewster's angle, reflected light is completely polarized, with the reflected and refracted rays perpendicular to each other.
### Formula
**theta_B = arctan(n2 / n1)**
At this angle, the reflected light contains only the s-polarization (perpendicular to the plane of incidence).

Lösungsbeispiel
Light reflecting off glass (n=1.5) from air (n=1).
- theta_B = arctan(n2/n1)
- theta_B = arctan(1.5/1)
- theta_B = arctan(1.5)
- theta_B = 56.31°
