Question
An unpolarised light is incident at an interface of two dielectric media having refractive indices of 2 (incident medium) and $2\sqrt{3}$ (medium) respectively. To satisfy the condition that reflected and refracted rays are perpendicular to each other, the angle of incidence is $\_\_\_\_$ .
Options
A.$60^{\circ}$
B.$10^{\circ}$
C.$30^{\circ}$
D.$45^{\circ}$
Solution
Brewester's law
$${tan\theta = \mu_{\text{rel~}} = \sqrt{3} }{\theta = 60^{\circ}}$$
