Answer
Snell's Law is also known as the "Law of Refraction" or "Snell-Descartes Law." It's named after Dutch mathematician Willebrord Snellius (1580-1626), who described it in 1621, though the principle was also independently discovered by French philosopher René Descartes. In some scientific literature, it's simply referred to as the "law of sines" in refraction.
