Question

Namethe medium which has highest and lowest optical density.​

Answer 1

Answer:

We know that,

A substance having higher refractive index has higher optical density.

From table 10.3, we can infer that.

Diamond has the highest refractive index (2.42)

Hence, it has the highest optical density.

Air has the lowest refractive index (1.0003)

Hence, it has the lowest optical density.

Answer 2

A medium which has the highest refractive index will have the highest optical density and vice-versa. It can be observed from table 10.3 that diamond and air respectively have the highest and lowest refractive index. Therefore, diamond has the highest optical density and air has the lowest optical density.
