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.

Answer:
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.
