Physical Science 20 - Jan 4

Welcome Back everyone.  I hope you all had a relaxing break and are ready to make the push to finals.  We starting back by learning about the rest of the properties of light that we didn't learn before the break and then went into looking at how the particle model of light fits into those properties.  As it turns out, assuming that light is made up of tiny spheres doesn't really do an adequate job of explaining all of lights behaviours.  We will now turn our focus to the wave model.  Before we do that however we have to try to understand what waves are.  That is where we are headed for tomorrow.  Today we covered slides 95-109 in the Physics Notes powerpoint.  Tomorrow we are going to start looking at waves and wave properties.
