Answer
Exam answer
(b) the path shown in option (b).
Explanation
The ray first undergoes total internal reflection and then refracts out.

From the figure given below, the refractive index of medium B with respect to medium A (ₐμᵦ) is:
(a) sin 45° / sin 30°
(b) sin 30° / sin 45°
(c) sin 45° / sin 60°
(d) sin 60° / sin 45°2026When a ray of light passes from a denser to a rarer medium, its wavelength ...............
