The refraction index, also known as refractive index, is an optical material Characteristic. It indicates the ratio by which the phase velocity of light in one medium is lower than in a vacuum. In ray optics, the refractive index is used in order to calculate the angle of deflection of a light beam on the boundary surface between two different materials.
