The refractive index can be linked to an important physical quantity, the relative speed of propagation of light in different media.

absolute refractive index is defined as a ratio of the speed of light in the vacuum and in selected medium  

relative refractive index is defined as a ratio of speed of light in two different media

When in relative refrective index ,second medium is vacuum then both will be same

Formula n=c/v
