Highest optical density = Diamond
Lowest optical density = Air
Optical density of a medium is directly related with therefractive index of that medium. A medium which has the highestrefractive index will have the highest optical density andvice-versa.
It can be observed from table 10.3 that diamond and airrespectively have the highest and lowest refractive index. Therefore,diamond has the highest optical density and air has the lowestoptical density.
