Answer 1

We know that,

Refractive index of the medium = Speed of light in air / Speed of light in the medium

Therefore,

Speed of light of the medium = Speed of light in air / Refractive index in the medium

Since Speed of light in air is always constant

Hence,

Speed of light in the medium = Constant/ Refractive index of the medium

Hence, we can say that

Lower refractive index of the medium, the higher is the speed of light.

The refractive index of

Kerosene is 1.44

Turpentine is 1.47

Water is 1.33
