Willebrord Snell is best known for his discovery regarding the refraction of light rays. This discovery, known as Snell's law, demonstrates that when a ray of light passes from a thinner element such as air, into a denser element, such as water or...

Snel is most famous for his research on the refraction of light, which yielded Snel's law. He also devoted a considerable amount of time to the calculation of geographic distances through trigonometric triangulation, and he is often credited with...

1580-1626 Dutch Physicist and Mathematician Willebrord Snell is remembered for discovering the law of refraction that bears his name. He has also been called the father of modern geodesy for perfecting the method of determining distances by...

1580-1626 Dutch mathematician and physicist who discovered the law of refraction of light rays, which states that the ratio sin i : sin r is a constant, dependent on the medium, where i stands for the angle of the incident ray and r for the angle of...

Willebrord Snellius[1] (born Willebrord Snel van Royen[2]) (1580–October 30, 1626, Leiden) was a Dutch astronomer and mathematician, most famous for the law of refraction now known as Snell's law. Snellius was born in Leiden, Holland. In 1613 he...
