5 station lab using sound and light teaching aids that should be available in the high school science storeroom. This lab covers the wave properties of reflection, diffraction, wavelength and frequency. Materials required are:
2-3 laser pointers
fixed position laser
3-4 tuning forks
Take 1-2 days for setup of this lab, however once you have it setup it will be good for years. I allow one 60 minute class period for this lab. I give 8 minutes per station.
