Question

Absolute Refractive indices of four different media a,b,c and d are respectively 1.4 ,1.1,2.1,1.8 arrange them in the increasing order of their optical densities

Answer 1

Answer:

1.1 , 1.4 , 1.8 , 2.1

The oprical density increase with the refractive index so more the refractive index more optically denser it is.
