| - Snell's law is a formula used for calculating the angle of incidence and the angle of refraction when light passes from one material into another. If light is travelling from medium 1 to 2, t states that where θ is the angle of incidence/refraction, n is the refractive index, and v is the velocity of light.
- Snell's Law is used to find the relationship between the angle of Incidence and Refraction and the indices of refraction of multiple mediums. Snell's Law can be used to find the refraction of a light ray in any situation, no matter what the different mediums(substances the light passes through) are.

* n is equal to the absolute index of refraction
* n is also equal to c/v which is speed of light in a vacuum divided by velocity
* is equal to the angle
- In optics and physics, Snell's law (also known as Descartes' law, the Snell–Descartes law, 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 and glass. The law says that the ratio of the sines of the angles of incidence and of refraction is a constant that depends on the media.

- In optics and physics, Snell's law (also known as Descartes' law, the Snell–Descartes law, 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 and glass. The law says that the ratio of the sines of the angles of incidence and of refraction is a constant that depends on the media. In optics, the law is used in ray tracing to compute the angles of incidence or refraction, and in experimental optics and gemology to find the refractive index of a material. Refraction of light at the interface between two media of different refractive indices, with n2 > n1. Since the velocity is lower in the second medium (v2 < v1), the angle of refraction θ2 is less than the angle of incidence θ1; that is, the ray in the higher-index medium is closer to the normal. Snell's law is also satisfied in the metamaterials which allow light to be bent "backward" at a negative index, with a negative angle of refraction. Named after Dutch mathematician Willebrord Snellius, one of its discoverers, Snell's law states that the ratio of the sines of the angles of incidence and refraction is equivalent to the ratio of velocities in the two media, or equivalent to the opposite ratio of the indices of refraction:
