The purpose of these notes is to understand interference in d>1 dimensions, particularly diffraction and diffraction gratings as appear in Lab 3. The most important parts to go over before doing the lab are the interpretation sections, Sections 3.2.2, 3.3.2, 4.2 & 5.2, and the formulas which go along with them, Eqs. 13, 17, 19 & 20.
