Question

The absolute refractive index of three medium are given below.In which medium ,will the light travel with its maximum speed and minimum speed
i)1.47
ii)1.36
iii)1.77

Answer 1

Answer:

The speed of light in a medium is maximum when the refractive index is minimum and the speed of light in a medium is minimum when the refractive index is maximum.

So, from the given refractive index,

Maximum speed of light => 1.36

Minimum speed of light => 1.77

Refractive Index:-

The refractive index is the physical quantity which is dependent on the speed of light in a particular medium.

It is basically the bending of light when it travels from one medium to the other. The bending depends on the speed of light in both the mediums.
