| GUIDES | |
| 1 | Waves Examples Definitions of quantities, explanations of equations, and worked out example problems. |
| 2 | Making Waves 1:
Transverse Waves Step-by-step illustration, description, and explanation of how a transverse wave is made in an elastic medium. |
| 3 | Making Waves 2:
Longitudinal Waves Step-by-step illustration, description, and explanation of how a longitudinal wave is made in an elastic medium. |
| 4 | Making Waves 3: Sound
Waves Step-by-step illustration, description, and explanation of how a sound wave is made in an elastic medium. |
| 5 | Speed of Sound Actually, the speed of waves in general. Shows how the speed of a wave depends only on the medium. |

Waves Begins With
an M - Presentation (QuickTime) 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. Waves Begins With an M Keynote 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! |
