"The refractive indices of water and air are approximately 1.333 and 1, respectively, so Snell's law gives us the relation which is impossible to satisfy. The critical angle θ crit is the value of θ 1 for which θ 2 equals 90°: Dispersion [ edit] Main article: Dispersion (optics) See more Snell's law (also known as Snell–Descartes law and ibn-Sahl 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 … See more Snell's law can be derived in various ways. Derivation from Fermat's principle Snell's law can be derived from Fermat's principle, which states that the light travels the path which takes … See more When light travels from a medium with a higher refractive index to one with a lower refractive index, Snell's law seems to require in some … See more In a conducting medium, permittivity and index of refraction are complex-valued. Consequently, so are the angle of refraction and the wave-vector. This implies that, while … See more Ptolemy, in Alexandria, Egypt, had found a relationship regarding refraction angles, but it was inaccurate for angles that were not small. Ptolemy was confident he had found an accurate empirical law, partially as a result of slightly altering his data to fit theory (see: See more Snell's law is used to determine the direction of light rays through refractive media with varying indices of refraction. The indices of refraction of the media, labeled $${\displaystyle n_{1}}$$, $${\displaystyle n_{2}}$$ and so on, are used to represent … See more In many wave-propagation media, wave velocity changes with frequency or wavelength of the waves; this is true of light propagation in most transparent substances other than a vacuum. These media are called dispersive. The result is that the angles … See more " - Refractive coefficient of wet ground
