Question

Which of the following materials has maximum optical density?(A) Glass
(B) Water
(C) Pearl
(D) Diamond

Answer 1

Answer of this question is diamond

Answer 2

Optical density is a scientific phenomenon which is the amount of the absorbed light ,while passing through an refractive object.

The optical density of various objects are completely different from each other.

Similarly,among the four substances mentioned in the question (water,glass,pearl and diamond).The maximum optical density is obtained by the diamond.

The optical density of the diamond is almost 2.417.
