Absolute refractive index: When the light is going from vacuum to another medium, then the value of refractive index is called the absolute refractive index.
Relative refractive index: When the light goes from one medium ( other than vacuum or air) to another medium then that refractive index is called relative refractive index.
Note: Refractive index of vacuum or air is 1.
The relative refractive index of medium 2 with respect to medium 1 is given as,
=
The absolute refractive index is given as,
Relation between absolute refractive index and relative refractive index can be wrtitten as
