Physical Science 20 - May 8

Today in class we went over Homework P5 Part B.  Afterwards I let students work on Assignment P2 for about 20 minutes and then we started to learn about critical angle and total internal reflection.  I showed the students some demonstrations on the topic and then we took some notes on it and went through one example.  The notes were on slides 57-59.  We didn't get to an assignment today with this but students need to make sure to hand in Assignment P2 tomorrow.  Tomorrow we will finish up learning about critical angle and total internal reflection and then get a chance to work on an assignment in it.
