Answer
Exam answer
The hypotenuse face.
Explanation
The ray undergoes total internal reflection there and the face behaves like a mirror.

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 ...............
