O knihe
High Quality Content by WIKIPEDIA articles! In optics and physics, Snell's law (also known as Descartes' law, the Snell-Descartes law, and the law of refraction), is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water and glass. The law says that the ratio of the sines of the angles of incidence and of refraction is a constant that depends on the media. In optics, the law is used in ray tracing to compute the angles of incidence or refraction, and in experimental optics to find the refractive index of a material. Refraction of light at the interface between two media of different refractive indices, with n2 n1. Since the velocity is lower in the second medium (v2 v1), the angle of refraction 2 is less than the angle of incidence 1; that is, the ray in the higher-index medium is closer to the normal. Snell's law is also satisfied in the metamaterials which allow light to be bent 'backward' at a negative index, with a negative angle of refraction.
