Physics 20 - Oct 9

Today we looked at the concept of the image and the 4 different image characteristics.  We finished the class by looking at plane mirror diagrams and showing how light reflects off of mirrors to see an image.  We didn't finished all of the diagrams but we will do that tomorrow. Assignment 2.2 was started at the end of class however we don't know how to do all the diagrams so the due date will be given after that.
