Refractive index is measure of bending of light ray while passing From one medium to another
If the the light ray coming from rearer medium such as air and incident on denser medium such as glass at angle of i and further gets refracted as it is passes from rearer medium to denser medium at angle of r the n=constant =Sin i/Sin r. Here n refractive index of the second medium with respect to first medium . Refractive index depend upon velocity of light
