Question 3:
Find out, from Table, the medium having highest optical density. Also find the
medium with lowest optical density.
Answer:
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.
