Question

define the refractive index and optical density

Answer 1

The physical density of a material refers to the mass/volume ratio.Optical density determines how much a light wave is slowed down as it passes through a medium. 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.

The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium.
