SNELL'S LAW: The ratio of the sine of the angle of incidence to the ratio of sine of angle of refraction is a constant for a light of a specified colour and for the specified pair of media.
MATHEMATICALLY,
sin i / sin r = constant
ABSOLUTE REFRACTIVE INDEX:
Nm = c / v
where Nm is the refractive index of the medium, c is the speed of light in vacuum and v is the speed of light in the medium.
Hope it helped
