Brewster's angle for glass
WebFor total internal reflection we know that the angle of incidence is the critical angle. So, θ1 = θc. θ 1 = θ c. However, we also know that the angle of refraction at the critical angle is 90 90 ° °. So we have: θ2 = 90∘. θ 2 = 90 ∘. We can then write Snell’s Law as: n1 sinθc = n2 sin90∘ n 1 sin θ c = n 2 sin 90 ∘. WebMar 13, 2024 · the Brewster angle reader instrument from various materials.
