    The refractive index is the angle waves (such as light) are bent when passing form one material to another. For example, as light passes from air through a glass of water.

    The absolute RI is the RI if the waves are entering a material from a vacuum.

    the index of refraction of a substances when the ray passes into it from a vacuum.

    It is the ratio between the speed of light in space and its speed in that medium OR It is the ratio between sine the angle of incidence in air and sine angle of refraction in that medium

    n=c/v where c=speed of light in space

    v=speed of light in medium
