Question

Number of waves in a length l traversed by a mono chromatic light in vacuum is $$106$$. When the same length of path is traversed by the same light in a medium other than vacuum, number of waves is $$3$$×$$106$$. When the same light travelling in vacuum, strikes the $$vacuum-medium$$ interface at an angle of incidence $$60o$$, after refraction, the ray will deviate through an angle of

Infinity Learn · Accepted Answer

In vacuum, $$l=n1$$λ, In the medium, μ$$l=n2$$λ∴ μ$$=n2n1=3$$×$$106106=3Now$$ $$sinr=sini$$μ$$=sin60o3=12$$⇒$$r=30o$$∴ δ$$=i$$−$$r=60o$$−$$30o=30o$$
