Absolute refractive index
Refractive Re*fract"ive (r?*fr?kt"?v), a. [Cf. F. r['e]fractif. See {Refract}.] Serving or having power to refract, or turn from a direct course; pertaining to refraction; as, refractive surfaces; refractive powers. [1913 Webster]

{Refractive index}. (Opt.) See {Index of refraction}, under {Index}.

{Absolute refractive index} (Opt.), the index of refraction of a substances when the ray passes into it from a vacuum.

{Relative refractive index} (of two media) (Opt.), the ratio of the sine of the angle of incidence to the sine of the angle of refraction for a ray passing out of one of the media into the other. [1913 Webster]
