Physical Science 20 - Dec 12

Today we went over the homework fro yesterday on indices of refraction.  We then learned about the laws that govern refraction.  These laws are similar to the laws of reflection with one exception.  The law that talks about the relationship between the angles is different.  It is called Snell's Law.  We looked at an example involving Snell's Law and then the students were given some home to work on. They had to do Assignment 3.1 as well as Part B of the Refraction Problem handout given yesterday.  This is due tomorrow.
