...Snell's law of refraction in optics, the rule that when a ray of light passes from one medium to another, the sine of the angle of incidence divided by the sine of the angle of refraction is equal to the ratio of the indices of refraction in the two media. For a ray passing from medium... | |

...translucent media. As a light beam strikes the boundary between two media, it bends in such a way that the sine of the angle of incidence divided by the sine of the angle of refraction is proportional to the ratio of the densities of the two media. In this context, the principle that... | |
