Questions
A transparent solid cylindrical rod has a refractive index of . It is surrounded by air. A light ray is incident at the midpoint of one end of the rod as shown in the figure.
The incident angle for which the light ray grazes along the wall of the rod is
detailed solution
Correct option is C
c = 90–r(1) sin90= μsinc = μcos r⇒cos r=1μ=32, r=30o(1) sinθ = μsin rsinθ=23 x 12=13 ; sinθ=13 θ=sin-113Talk to our academic expert!
