Geometry Review
 Answers The description of interference patterns involves right triangles and the use of some trigonometry. Here's a bit of directed review.

Line Density Math
 Answers How far apart are the lines of a diffraction grating if the line density is given as 440 lines per millimeter? Not a trivial or intuitive problem. This sheet walks students through the process.

Optics Begins With an M Part of the "Physics Begins with an M" series. Make a transperency and put it on the overhead on the first day of the unit to enhance curiousity in the material of the unit. Wave Optics Begins With an M Keynote  Presentation (QuickTime) A nifty Keynote presentation of the M's. (Keynote is Apple's presentation software; PowerPoint is Microsoft's presentation software.) Trust me, neither Keynote nor PowerPoint are The Great Saviors of education. I recommend using them sparingly if at all. Better to teach!
