velocity of light and refractory index#
Refractive index means RI of your medium with respect to some other medium. 1μ2 means RI of medium two with respect to medium one.
Now absolute refractive index means when your first medium is vacuum or air(if the calculations are not that precise). Because 1μ2= μ2/μ1
Now if μ1 is vacuum or air, it is equal to 1. so you remain with 1μ2=μ2 which absolute refractive index.

The refractive index of the medium is inversely proportional to the velocity of light in it. As the refractive index of a medium increases, the speed of light going through that medium decreases. ... The relation between phase velocity of monochromatic light in dispersive medium with speed of light in vacuum is v = c/n.
