Lab Day for Waves

Demonstrated Belly-Dancing Tuning Forks.

Set up Dave Cross Wave Machine. Students were asked to determine how the wave speed depends on the number of nodes and the tension in the string.

Set up resonance tube with water. Students were asked to calculate the resonant depths and then verify by experiment.

Snell's Law Lab. Students were asked to measure the index of refraction of water and calculate the speed of light in water.

Reviewed results for the last 20 minutes of class.
