Snell's Law with verification

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 there is a verification stage in which students can see the solution with the measurements for a given experimental setup. If students shouldn't be able to see the solution, see the alternative "Snell's Law" version of the laboratory instead (without verification).
