Physical Science 20 - April 28

Today student handed in their assignment from yesterday,  Assignment P1.  Today we learned how to find the image and its characteristics mathematically using a set of formulas.  We talked about how to use the formulas and how to interpret the results.  We then went through a couple of examples, one for a converging mirror, one for a diverging mirror.  After this students had some time to work on Homework P4.  We will take this up on Monday and then start into refraction.  The notes today were on slides 32-37.
