Find out, from Table, the medium having highest optical density. Also find the medium with lowest optical density

Material medium Refractive index Material medium Refractive index
Air 1.0003 Canada Balsam 1.53
Ice 1.31 - -
Water 1.33 Rock salt 1.54
Alcohol 1.36 - -
Kerosene 1.44 Carbon disulphide 1.63
Fused quartz 1.46 Dense flint glass 1.65
Turpentine oil 1.47 Ruby 1.71
Benzene 1.50 Sapphire 1.71
Crown glass 1.52 Diamond 2.42

 

Best Answer

Lowest optical density = Air

Highest optical density = Diamond

The optical density of a medium is directly related to its refractive index. A medium with the highest refractive index will have the highest optical density and vice-versa.

It can be observed from the table that air and diamond respectively have the lowest and highest refractive index. Hence, air has the lowest optical density and diamond has the highest optical density.
