Snell's law (also known as the Snell–Descartes law, the ibn-Sahl law, and the law of refraction) is a formula used to describe the relationship between...

Snell's window (also called Snell's circle or optical man-hole) is a phenomenon by which an underwater viewer sees everything above the surface through...

made of material with index of refraction n {\textstyle n} . Applying Snell's law, light entering the first surface is refracted according to sin ⁡ i =...

credited Ibn Sahl with discovering the law of refraction [23], usually called Snell’s law and also Snell and Descartes’ law." Smith, A. Mark (2015). From Sight...

another through a flat surface. This is easily shown by rearranging Snell's law to find that n sin θ is constant across an interface. In air, the angular...

is bent, or refracted, when entering a material. This is described by Snell's law of refraction, n1 sin θ1 = n2 sin θ2, where θ1 and θ2 are the angle of...

extraordinary refraction of a calcite crystal "violates Snell's law", we mean that Snell's law does not apply to the extraordinary ray, because the direction...

{\displaystyle x} axis. Snell's law for refraction requires that these terms be equal. As this calculation demonstrates, Snell's law is equivalent to vanishing...

mathematician, commonly known as Snell. His name is usually associated with the law of refraction of light known as Snell's law. The lunar crater Snellius is...

angles is given by the law of reflection: θ i = θ r , {\displaystyle \theta _{\mathrm {i} }=\theta _{\mathrm {r} },} and Snell's law: n 1 sin ⁡ θ i = n 2...
