Physical Science 20 - June 6

Today in class we started looking at the wave property of interference.  This involved learning about the principle of superposition and what a resultant wave looks like.  We learned a technique for drawing a resultant wave and just finished an example before the bell went.  This was all covered on slides 141-158.  Homework 5.4 was assigned at the end of class and students will get some time tomorrow to work on it.
