Waves and sound

Preset water for power off, water off, which happened.

Set up for a packed session. The little round bottom flask proved very useful as a way to demonstrate the fundamental frequency varying with the amount of water. The rock was used to chime the rebar. The kettle proved superfluous. 

The PVC pipe was used to demonstrate the first overtone and the fundamental frequency.

The sidewalk was used as the student center did not make a good imprint last term.

Work was then done on the board. Followed by the sound demonstrations including the web sites. 

Lab was indoor with resonance tubes.
