...correction in 1604. The laws of single refraction may be stated as follows: 1. At any angle of incidence the ratio of the sines of the angles of incidence and refraction is constant for the same two media, but varies with different media, and this ratio is called the index of refraction.... | |

...the angle of incidence equals the angle of reflexion. The direction of the refracted ray is such that the ratio of the sines of the angles of incidence and refraction, is constant for the same media. The scattered rays proceed from the point of incidence as from a self-luminous point.... | |
