Refraction (2 of 5) Snell's Law, Calculating Angle of Refraction and Angle of Incidence

Shows how to use Snell's law to calculate the angle of refraction, the angle of incidence and also to index of refraction. Refraction is the change in direction of a ray of light as it passes from one medium to another. The amount of refraction is determined by the index of refraction of the media and the angle of incidence. For light, refraction follows Snell's law, which states that for a given pair of media, the ratio of the sines of the angle of incidence and angle of refraction (sin θ1 / sin θ2) is equal to the ratio of the two the indices of refraction (n2 / n1) of the two media.
