Bending of light at the boundary of two medium is called refraction.
The light bending ability of that particular medium is called refractive index.
Refractive index is defined as ratio of sine of angle of incidence to sine of angle of refraction.
It is denoted by n or μ.
Thus, refractive index is given by,

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.
