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) → ∞.
WebAt brewster’s angle, the reflected ray and the transmitter ray are at right angles, i.e; θr + θt = 90˚, where θt is the transmitted angle. We can rewrite this as, θt = 90˚ - θr. We know from the law of reflection, θi = θr. So we get, θt = 90˚ - θi. So at brewster’s angle, (1) can be rewritten as, Advertisement.
