Physical Science 20 - May 10

Today in class we went over Part C to Homework P5.  We then started looking at an application of refraction.  We learned some terminology involved with studying lenses and optics.  This didn't take too long.  After which, we watched a video on optics.  There was no assignment today.  The notes were on slides 64-72.  Tomorrow we will look at finding images in lenses graphically.
