Absolute refractive index is the refractive index when a light ray passes from air to the given medium or from a medium to air.
We thus apply Snell's law as follows(for a ray going from air to a medium),
n a sin i = n m sin r
where n m is the refractive index of the medium
n a is the refractive index of air
i is the angle of incidence
r is the angle of refraction
Make n m the subject in the above equation
n m = n a sin i sin r
n a = 1
n m = sin i sin r
Also, another definition says that n m = c c m = s p e e d   o f   l i g h t   i n   v a c u u m s p e e d   o f   l i g h t   i n   t h e   m e d i u m
