A transparent medium is sometimes said to have a high optical density (or to be relatively dense) if it has a high refractive index.
I predict you are talking about the refractive index. the higher the value, the more dense the substance and thus light undergoes greater refraction (bending of light as it passes thru different mediums) the refractive index = sin of the angle of light made with normal in the less dense medium divide by the sin of angle in the denser medium.
Optical dense refers to the index of refraction. If one medium is optically denser than another, then its index of refraction is larger, meaning the speed of light in the optically denser medium is smaller.
Optical dense refers to the index of refraction. If one medium is optically denser than another, then its index of refraction is larger, meaning the speed of light in the optically denser medium is smaller.

Refractive index of vacuum is 1.

Using Snell's law, n(1)=(n(2) x sin angle (2)) / sin angle (1).n(1)= The refractive index of the more optically dense medium.n(2)= The refractive index of the less optically dense medium.angle (1)= The critical angle of the two mediums.angle (2)= 90 degrees since when light is at the critical angle it undergoes total internal reflection.Since sin 90= 1, this can be ignored, resulting in n(1)= n(2) / sin angle (1)
No, if the refractive indexes of the two mediums are exactly identical it will be invisible.

The refractive index of air is about 1.0003, and of quartz about 1.45, so quartz is the more "optically dense" medium in this situation. When light goes from a less dense medium to a more dense medium, it is refracted toward the normal. The normal is the imaginary line perpendicular to the surface where the light enters.
The optical density of a medium is not the same as its physical 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. 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. A medium with a low optical density, would have also a low refractive index.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.

"The refractive index of water is 4 / 3" means the refractive index of water with respect to air. "The refractive index of glass is 3 /2" means the refractive index of glass with respect to air. You change the question as ," what is the refractive index of glass with respect to water? The answer is it is the ratio of refractive index of of glass with respect to air to the refractive index of water with respect to air =( 3/2) divided by( 4/3) = 1.125
I assume "molecular refractive index" refers to "the refractive index of a group of molecules". In this case, you just use the units for a refractive index - i.e., a dimensionless number.
