Webrefraction Snell’s law, in optics, a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each. This law was discovered in 1621 by the Dutch astronomer and mathematician Willebrord Snell (also called Snellius). Webnr = index of refraction of the refractive medium. This relationship between the angles of incidence and refraction and the indices of refraction of the two media is known as Snell's …
