One of a system of diverging lines passing through a point, and regarded as extending indefinitely in both directions. See Half-ray. Bundle of rays. (Geom.) See Pencil of rays, below. Extraordinary ray (Opt.), that one or two parts of a ray divided by double refraction which does not follow the ordinary law of refraction. Ordinary ray (Opt.) that one of the two parts of a ray divided by double refraction which follows the usual or ordinary law of refraction. Pencil of rays (Geom.), a definite system of rays.
