Physical Science 20 - April 25

Today students handed in their labs from yesterday and then we learned about image characteristics and the laws of reflection.  We discussed the difference between specular and diffuse reflection and then students were assigned Homework P3.  This will be checked tomorrow.  Students are to start to bring a protractor and a ruler to the class on a regular basis.  Tomorrow we will begin to look at curved mirrors and how to find images in them.  The notes today were on slides 18-26 of the Physics Notes powerpoint.
