For 10 points, name this law that can be used to explain the bending of light when it enters and exits glass and water from the air.
This law was originally discovered by Descartes under the name the Law of Sines. This law can be used to express an equation for finding the polarizing or Brewster's angle. When one part of this law exceeds the critical angle, the result is called total internal reflection. This law equates the angles of incidence for a wave entering a new medium to the indices of refraction for those mediums.
