Bookmark or Share- Snell’s law | Definition, Formula, & Facts | BritannicaSnell’s law, in optics, a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each. This law was discovered in 1621 by the Dutch astronomer and mathematician Willebrord Snell (also called Snellius).
- 折射定律 - 百度百科折射定律也称为斯涅尔定律（ Snell's Law ）。 光线通过两介质的界面折射时，确定入射光线与折射光线传播方向间关系的定律，几何光学基本定律之一。
- Snell's law - WikipediaSnell's law (also known as the Snell–Descartes law, the ibn-Sahl law, [1] and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.
- Snell's Law: Formula, Diagram, and Derivation - Science FactsSnell’s law gives a relationship between the angles of incidence and refraction. In order to understand this relationship, it is critical to know the refractive indices of the two mediums. The history of Snell’s Law goes back to 1621 when Dutch astronomer and mathematician Willebrord Snell discovered the laws of refraction.
- 斯涅尔定律 - 维基百科，自由的百科全书當光波從一種介質傳播到另一種具有不同折射率的介質時，會發生折射現象，其入射角與折射角之間的關係，可以用斯涅尔定律（英語： Snell's law ）來描述。
