Physical Science 20 - Jan 12

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.  Reminder that tomorrow Assignment 5.1 is due.  Students will be handing this in. Tomorrow we will look at specific interference patterns called standing waves.
