Question

How is Refractive inden related to optical density??
​

Answer 1

Answer:

The more optically dense a material is, the slower that a wave will move through the material. The refractive index is a measurement of optical density. ... For example air, having a low optical density has a refractive index of 1.0003, whereas water, with a higher optical density, has a higher refractive index of 1.333.
