how to find the speed of light using snells law. The indices of refraction of the media labeled n 1 displaystyle n_1 n 2 displaystyle n_2 and so on are used to represent the factor by which a light rays speed decreases when traveling through a refractive medium such as glass or water as opposed to its velocity in a vacuum. 30 1 0 8 m s 1.

Snells Law states that the ratio of the sine of the angles of incidence and transmission is equal to the ratio of the refractive index of the materials at the interface. L-x b2 l-x2 sinϴ2. Find the angle of incidence if the refracted ray is at 14 degrees the refractive index is 12.
Here x x2 a2 sinϴ1 and.
Find the angle of incidence if the refracted ray is at 14 degrees the refractive index is 12. So dTdx sinϴ1v1 sinϴ2v2 0. Snells Law is written as. Snells law compactly describes what happens to the trajectory of a beam of light as it passes from one medium such as air to another such as glass.
