Mini-module

We have a new learning module ready for this week. It is a mini-module, covering a selection of wave concepts we need for studying electromagnetism. So the concept guide is a bit shorter, but I made the mini-quiz a bit larger than usual, just to give you some extra workouts.

Also, I will be podcasting exercises 16 and 20 in chapter 15, p. 312. Keep an eye on Announcements, when I am ready to publish them.
