Physical Science 20 - June 13

Today in class we looked at how waves behave in two dimensions.  I introduced some important terms like wavefronts and rays and then we examined some properties.  We learned what happens with waves when the reflect off of a barrier.  After that we examined some more properties of two dimensional waves.  We spent some time learning how waves refract and how they diffract.  This was all covered on slides 168 - 186.  Students were assigned Homework 5.6 and asked to have that completed for tomorrow.  Tomorrow we will learn about how these waves interfere with each other.  Reminder that tomorrow is your wave quiz on vibrations, superpositioning and the universal wave equation.
