Rare term; more commonly referred to as スネルの法則 (Snell's law). Used in physics contexts.
See also: スネルの法則
The law of refraction explains how light bends at the boundary between different media.
スネルの法則 is the standard modern term for Snell's law; 屈折の法則 is a rare synonym that directly translates 'law of refraction'.
Compound of 屈折 (refraction) + の (possessive particle) + 法則 (law). A direct translation of the English term 'law of refraction'.
