Physical Science 20 - Jan 6

Today we went over Homework 5.1.  Afterwards we started to learn about waves.  We learned about the concept of the medium as well as the different types of mechanical waves.  Transverse waves were discussed along with the terms used to describe those types of waves as well as longitudinal waves and terms associated with them.  We also learned about a measurement called the wavelength.  This was all covered on slides 123-132.  Tomorrow we will start examining wave properties with a hands-on activity.
