Question

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

Answer 1

The optical density is highest for Diamond and lowest for Air. Optical density is directly proportional to the refractive index of a medium; a higher refractive index corresponds to a higher optical density, and conversely. Table 10.3 indicates that diamond and air possess the highest and lowest refractive indices, respectively. Consequently, diamond exhibits the greatest optical density, while air has the least.
