Physical Science 20 - Dec 3

Today we went over Homework 2.4 on the pinhole camera.  Then we started looking at the laws of reflection.  We learned some vocabulary that will be important as we study light.  We then learned about the 3 laws the govern how light reflects.  This led into a discussion on what reflects light and how that happens.  We the talked about the difference between specular and diffuse reflection.  Students then learned how we see reflections in mirrors and what a line a sight means.  This led into a discussion on image characteristics.  This was covered on slides 16-22 in the Physics Notes powerpoint.  We didn't get to Homework 3.5 today but we will get there tomorrow.
