WebDec 27, 2024 · The Brewster angle is θ B = arctan ( n 2 / n 1), where n 1 is the refractive index for the light incident on an interface, which has a value whichever of n 1 or n 2 is greater. This angle is always less than the critical angle for total internal reflection, θ c = arcsin ( n 2 / n 1), where a critical angle exists ( n 1 > n 2 ), since arcsin ... Web2.4.2.2 Brewster angle. We now want to have a closer look at the Fresnel equation for the parallel component of the reflectivity: (2.75) The incident angle α that leads to the combination α + β = 90 degree is named Brewster angle. In this case, the reflectivity for the parallel component vanished due to tan (90 degree) → ∞.
