The law of refraction relates the angle of incidence (angle between the incident ray and the normal) to the angle of refraction (angle between the refracted ray and the normal).

Thus, the law of refraction predicts that a light-ray always deviates more towards the normal in the optically denser medium: i.e., ... The law of refraction, which is generally known as Snell's law, governs the behaviour of light-rays as they propagate across a sharp interface between two transparent dielectric media.

Refraction explained ... The law of refraction ... The actual law of refraction was discovered in the early 1600s by a Dutch mathematician and geodesist, Willebrord Snel van Royen. (Because his name in Latin is “Snellius”, the law is often called “Snell's law” instead of “Snel's law”.

As can be inferred from Stigler's Law of Eponymy, the fact that the law of refraction is named after Snel automatically implies that he was not the first person to discover it.

Snell's Law relates the indices of refraction n of the two media to the directions of propagation in terms of the angles to the normal. Snell's law can be derived from Fermat's Principle or from the Fresnel Equations.

1.1 Introduction Snell's law of refraction is the fundamental law that governs geometrical optics. We begin, therefore, with the proof of this basic rule, as it has been verified by Fermat. We then demonstrate how this surprisingly simple law can be applied to graphical ray tracing. ... chapter 1, Law of Refraction:
