 When a ray of light passes from one medium to another, it is refracted so that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities in the two media.

...refracting medium (I:11). (5) The angle of incidence always equals the angle of reflection (11:2). (6) The ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for any pair of media (I1:4). Barrow briefly justifies these hypotheses by appeal to simple... | |

...Refraction The law in question is the assertion that, when a ray of light passes from one medium to another, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant characteristic of the pair of media. The law was discovered experimentally by Harriott,... | |

...Another example is Snell's Law: "A ray of light, incident at a surface separating two media, is bent. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant for two given media." As stated, the law is a theorem in the theory of optics that can be... | |
