Physical Science 20 - May 30

Today we began looking at waves by studying what causes waves.  We learned about periodic motion and how waves are generated.  Terms such as frequency and period were discussed as well as other important concepts such as phase difference and resonance.  These notes were on slides 110-119. We finished of by watching a video on resonance.  This video is located in the Physical Science 20 course video list.  Tomorrow we will look at another example relating frequency to period and then get some time to work on the assignment associated with this.
