Tuesday, you will get your exams back. Based on how they went and a few other factors, tomorrow we'll spend most our time solving exam problems and going over the current homework problems. We'll not cover much new material (other than what is relevant to the homework), and move on to diffraction on Thursday.
Part of the reason I'm skipping over some of the chapter on interference is that most of the last half is just straightforward applications of what we did already - superimposing two sources in, say, a Michelson interferometer and figuring out the interference condition from the geometry. Ditto for antireflective coatings, for the most part. So, we'll not cover a lot of that material in class, it will be up to you to read about those applications on your own. All you really need beyond what we've covered is more geometry, and accounting for the refractive index changing at an interface.
The gist of this is that if you (a) feel fine about the exam, (b) have done the homework already, and (c) will actually read the chapter, you won't miss much tomorrow. Thursday we start diffraction, which is also really more of the same, modulo a semantic argument I will mock briefly. ;-)
