Wave Interference and Reflection

Today was a pretty laid-back day because I wanted you to actually finish your homework in class. There were some notes (below), but mostly we looked at simulations online (also below). You then had one last assignment to practice stuff from this unit because YOUR TEST IS THURSDAY. I also gave out the practice test (yet another link below).
