Question

a) Is the refractive index of a medium an indicator of its optical density ? How?
​

Answer 1

Answer:

Yes

Explanation:

It is the basic measure ment of density

If any object bends away from normal then it has different density and even if it bends towards the normal then it has different density

Answer 2

Answer:

yes, refractive index of a medium is an indicator of its density

Explanation:

retractive index is directly proportional to the optical density of a medium;

more the refractive index, more is the density
