Physical Science 20 - Dec 9

Today in class we went over the answers to Homework 2.6.  After that, we learned how to draw ray diagrams for curved mirrors.  This allows us to discover the image characteristics by use a graphical approach.  Students were given the instructions on how to draw 3 rays of light from an object to a mirror and reflect them off of the mirror to locate the image.  The students then had a chance to work on Assignment 2.3, which was simply a series of ray diagrams that students had to work through to figure out the image characteristics.  I had originally assigned this to be due tomorrow but I am changing that now until Thursday.  This will be handed in however.
