Question

The medium having the highest optical density and the medium having the lowest optical density..???

Answer 1

Highest optical density = Diamond


Lowest optical density = Air

Optical density of a medium is directly related with the refractive index of that medium. 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.

Answer 2

HERE IS UR ANS:-

The medium having highest optical density - Diamond

Medium having lowest optical density - Air

This is because the medium having highest refractive index possess highest optical density.

The medium having lowest recractive index possess lowest optical density.

Refractive index is measured as the extent of bending of ray of light.

In a denser medium ray of light bends more, as its speed gradually decreases while coming from rarer to denser medium.

Thus is the reason why optically denser medium has high refractive index.

Similarly, ray of light bends less in less denser or rarer medium. While coming from denser to rarer medium speed of ray of light increases, therefore it bends less.

This is the reason why optically rarer medium have less refractive index.
