Find the maximum angle of refraction when a light ray is refracted from glass $(μ = 1.50)$ to air.

Open in App

Solution

From the definition of critical angle, if refracted angle is more than $90^{\circ}$ , then reflection occurs, which is known as total internal reflection. So maximum angle of refraction is $90^{\circ}$ .
