...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... | |

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.
