Find out, from Table 10.3, the medium having highest optical density. Also find the medium with lowest optical density

Table 10.3 NCERT - Refractive Index of Some Media.jpg



We know that,

A substance having higher refractive index has higher optical density.


From table 10.3, we can infer that

Diamond has the highest refractive index (2.42)

Hence, it has the highest optical density.


Air has the lowest refractive index (1.0003)

Hence, it has the lowest optical density.
