Question

Who discovered Snell's law?

Answer 1

Answer:

Willebrørd Snell

Open any physics textbook and you'll soon come across what English-speaking physicists refer to as "Snell's law". The principle of refraction – familiar to anyone who has dabbled in optics – is named after the Dutch scientist Willebrørd Snell (1591–1626), who first stated the law in a manuscript in 1621.
