Question

Refractive indices of four media A, B, C and D are given below:
Medium Refractive index
A 1.33
B 1.44
C 1.52
D 1.65
In which of these four media is the speed of light (i) maximum, and (ii) minimum?

Solution

The refractive index of a medium is related to the speed of light as follows:

$Refractive index=SpeedoflightinvacuumSpeedoflightinamedium$

Since the speed of light in vacuum is a constant, the refractive index becomes inversely proportional to the speed of light in a medium.
(i) The speed of light is maximum in a medium that has the lowest refractive index, i.e., medium A.
(ii) The speed of light is minimum in a medium that has the highest refractive index, i.e., medium D.
