You can analyze this by using the equation n=c/v. N is the index of refraction, c i the speed of light, and v is the velocity of light (that is going from itself to the other medium) in the substance that it goes through and then refracts. If you go from a small refractive index to a larger refractive index, then light refracts toward the normal. If you go from a large refractive index to a smaller refractive index, then the light refracts away from the normal.
