Refractive index is measure of how much the speed of light is slowed when passing through a material possessing refractive index other than one,because refractive index is one for air/vacuum in which speed of light is 'c'. ... It's totally independent of angle of incidence of light.

Dear student 
Snell's law is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves, passing through a boundary between two different media, such as water and glass. The law says that the ratio of the sine of the angle of incidence and of refraction is a constant that depends on the media. So, light changes direction when it passes through different media (glass to air, air to water, etc.). Snell’s law is used to calculate the amount of refraction (deviation), or to tell you the refractive index of the materials. Snell's law states that the ratio of the sine of the angle of incidence and refraction is equivalent to the ratio of velocities in the two media, or equivalent to the opposite ratio of the indices of refraction.
Good Luck
