Snell's Law

Snell's law (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.

In this laboratory you can experiment with several lenses to find the refractive indices of different materials using this law.

In this version of the laboratory students will have to measure by themselves using the squares grid. The refraction angle is not given to them. An alternative version of the laboratory is available in which a verification stage is available with the resulting refraction angle. See "Snell's Law with verification" for that version.
