Physics 20 - Nov 5

We started the class today by going over Homework 3.3.  After that was taken up, then we looked at the phenomenon of total internal reflection and how that occurs.  The concept of the critical angle was covered and Homework 3.4 was given.  It is due tomorrow.  As well, be ready for the refraction quiz that is tomorrow.  Check yesterdays post to see what you need to study.
