Today we went over Homework 5.4 and then we learned about how waves behave in 2 dimensions. Wave behaviour in 2D is slightly different then in 1D but really similar to light behaviour. We looked at the properties of reflection and we started in on refraction. This was covered on slides 148-158. Students had a little bit of time to work on Homework 5.5, which will be due tomorrow.
Tomorrow we will finish up the waves unit by looking at the rest of refraction and diffraction.
