Topic: Ray path through a prism
Question wording verified against source paper
Answer
Solution diagram
Exam answer
Ray J undergoes total internal reflection at the vertical face and then emerges normally through the horizontal base.
Explanation
Complete the ray path with the reflected ray and the normal emergence as in the source diagram.

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