As the mass of the object increases, the refractive index decreases.,

As the optical density increases, the refractive index increases.
As the optical density increases, the refractive index increases.

As the physical density of the substance increases, the refractive index increases.

As the physical density of the substance increases, the refractive index increases.

As the mass per unit volume of the substance increases, the refractive index decreases.
