What is Snell’s Law?
In this post, we predict quantitatively, using Snell’s Law, the refraction and total internal reflection of light in a variety of situations, as a part of the Prelim Physics course under the module Waves and Thermodynamics and sub-part Ray Model of Light. Snell’s Law is a law that states that the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media. n_{1} sin \theta _{1} = n_{2} sin \theta _{2}
The following two videos introduce you to Snell’s Law, and goes over an example question.
