Subsequently, one may also ask, how does refractive index relate to density?
The index of refraction value of a material is a number that indicates the number of times slower that a light wave would be in that material than it is in a vacuum. So as the index of refraction value increases, the optical density increases, and the speed of light in that material decreases.
Additionally, what is the relationship between optical density and mass density? Answer: Optical density should not be confused with mass density, which is mass per unit volume. It is possible that mass density of an optically denser medium may be less than that of an optically rarer medium (optical density is the ratio of the speed of light in two media).
Correspondingly, is refractive index directly proportional to density?
In general, if the density of the medium increases than refractive index of that medium also increases. However, of course there are some exceptions like water. Velocity of the light in a medium is inversely proportional to the refractive index of that medium.
How is optical density related to refractive index which medium has highest and lowest optical density?
A medium which has the highest refractive index will have the highest optical density and vice-versa. It can be observed from table 10.3 that diamond and air respectively have the highest and lowest refractive index. Therefore, diamond has the highest optical density and air has the lowest optical density.
