Hey mate !!!
During refraction of light,light follows the snells law.
=> Sin i/sin r = Constant or
=>n1 Sin i = n2 Sin r
Hope it helps !

According to the Snell's law,
The ratio of sine of angle of incidence to the sine of angle of refraction is constant.
sine of angle of incidence(i)/sine of angle of refraction(r)=constant
this constant is called refractive index(n).
n=sin i/sin r
