GUIDES
1 Waves Optics Examples
Definitions of quantities, explanations of equations, and worked out example problems.
2 Scattering
A descriptioon of scattering and a thorough explanation of why the sky is blue.

Geometry Review - Answers
The description of interference patterns involves right triangles and the use of some trigonometry. Here's a bit of directed review.
2
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.

Wave 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!
  Mechanical Universe: The Wave Nature of Light
This episode covers tthe electromagnetic spectrum, reflection, refraction, interference, diffraction, and scattering. Alternate forms accommodate students seated side-by-side.
4 Wave Optics Crossword Puzzle Grid - Clues [in progress]
Crossword puzzles are highly personalized and may not always translate well from my classroom to yours.
