Explanation:

Refractive index, µ = c

(speed of light in vaccum) v

(speed of light in any medium) c

(1) Hence refractive index of a medium is inversely proportional to the speed of light in that medium.

(2) Refractive index is inversely proportional to the angle of refraction.

From (1) and (2) Velocity of light is directly proportional to the angle of refraction. Thus velocity of light is minimum in medium R because angle of refraction is 150.
