Physical Science 20 - May 1

Hello everyone.  Today we went over Homework P4 and then started into our next property of light - the property of refraction.  This is how light behaves when it passes through substances.  When light moves from one substance to another, it will change paths or bend.  We learned some new terminology today as well as why this bending happens.  Notes today we from slides 43-51.  Students then had some time to work on Part A from Homework 3.5.  We will take this up tomorrow.
