Question

What do you mean by the optical density of a medium?What is its relation with the refractive index of that medium?


Explain properly.

Answer 1

Optical density is the degree to which a refractive medium delays transmitted rays of light. But Refractive medium itself contains the Optical Density.
Actually Optical density is the density through which an object can be viewed. Actually it is the degree of the density to which a refractive medium( mirror or some transparent objects) will slow down the speed of the light rays which are transmitted. And the Optical Density lies inside the Refractive Medium itself

Answer 2

Answer:

the ability of a medium to refract light is expressed in terms of its optical density . optical density has a definite connotation . it is not the same as mass density.
