| P118 : P118 - Traveling Wave |
|
| Two different segments of a ?slinky? spring are stretched on the stage of an overhead projector to display sine waves of two different wave lengths. Turning the crank marches the wave along in order to facilitate phase and phase angle discussions by making marks on the projected image. |

| P815 : P815 - Super Slinky with Stand |
|
| A longer “slinky” spring for wave demonstrations in the gymnasium or hallway allowing students more time to conceptualize the behavior of pulses, traveling waves, and standing waves. The worry about tangling during use, and especially during storage, is nicely handled with the included stand that allows easy deployment, retrieval, and storage. Slinky size: 3" diameter by 8" long compressed, can be stretched up to 6 feet. |
