Question

The absolute refractive indices of water glass and diamond are 1.77, 1.50 and 2.72 respectively, which medium is most optically denser ?(A) Water
(B) Glass
(C) Diamond
(D) None

Answer 1

Explanation:

B.....

I think so...............

Answer 2

Answer:

Explanation:

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

So, refractive index is inversely proportional to speed of light in medium.

Also, optical density is inversely proportional to speed of light.

Hence, diamond is the answer, hope you understood
