Answer 2

Explanation:

We define refractive index of one medium with respect to another as the ratio of velocity of light in the two mediums.

For absolute refractive index the first medium has to be vacuum and second is the medium of interest.

Speed of light in vacuum is c

And the speed of light in medium of interest is v.

Refractive index of air with respect to medium is v/c

Since the maximum velocity of light is in vacuum and the value is 3 into 10 power 8

Definitely v will be less than c

So the ratio will be less than 1.

Show the absolute refractive index can never be greater than 1.

But the relative ones for example the refractive index of oil with respect to air can be greater than 1 if the speed of light in oil is greater than that in air.
