Physical Science 20 - April 13

Today students learned about another property of light.  This one is called the rectilinear propagation of light or simply put, the fact that light travels in straight line.  We learned this with the use of a piece of technology called a pinhole camera.  This allowed us to discover the magnification equation.  We went through an example involving the magnification equation.  This was all covered on slides 9-16 of the Physics Notes powerpoint.  I assigned Homework P1 today as well as Homework P2.  Work on those over the break and we will go over the answers to them after the Easter Break.  Have a great break everyone!
