refractive index of a medium is equals to the ratio of speed of light in that medium to the speed in vacuum
sorry reciprocal of the ratio i previously wrote

to find refractive index, use n=sin i/sin r, where n is refractive index, i is angle of incidence, and r is angle of refraction
also you can use the formula n=speed of light in air/speed of light in medium
-n is refractive index of the medium
also, if you know the critical angle C, n=1/sin C
