Question

On a glass plate a light wave is incident at an angle of 60° . If the reflected and refracted waves are mutually perpendicular, the refractive index of material is : (A)  (1/√3)  (B)  (3/2)  (C)  √3  (D)  (√3/2)

By Brewsters law, μ= tan ip μ= tan 60°=√3

Q. On a glass plate a light wave is incident at an angle of $6 0^{\circ}$ . If the reflected and refracted waves are mutually perpendicular, the refractive index of material is :

$\frac{1}{3}$

$\frac{3}{2}$

$3$

$\frac{3}{2}$

By Brewsters law, $μ = tan i_{p} μ = tan 6 0^{\circ} = 3$
