Define critical angle in physics

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 … WebCritical angle (optics), the angle of incidence above which total internal reflection occurs.
