A light ray traveling from a higher index of refraction medium into a lower index of refraction medium (for example, from water into air) would bend away from the normal to the medium surface. When the refracted ray is parallel to the boundary of the medium, ?2= 90°. The incident angle, ?1, becomes ?c, called thea. critical angleb. Cauchy anglec. classic angled. conjugate angle
