Physical Science 20 - Jan 11

Today we learned about the universal wave equation.  This equation applies to all waves and is pretty simple to use.  The notes we took today we covered on slides 135-140.  Students were assigned Homework 5.2 and Assignment 5.1 today.  We will take up Homework 5.2 tomorrow and Assignment 5.1 will be handed in on Wednesday.  Tomorrow we will look at the interference of waves.
