Question

Unpolarized light is incident on a plane glass surface having refractive index . The angle of incidence at which reflected and refracted rays would become perpendicular to each other is :

Answer 1

Explanation:

Solution :

μ=tanip=1.5μ=tan⁡ip=1.5

ip=tan−1(1.5)=56.3∘ip=tan−1⁡(1.5)=56.3∘

The reflected ray and the refracted ray will be perpendicular to each other when the angle of incidence = polarizing angle ip
