C4 practical: Speed of sound (drinking straw) simulation
Using Paul Falstad's ripple tank simulation it is possible to add walls to form pipes and then adjust the frequency to obtain resonance, the resonating pipe can then recorded and the video analysed with loggerpro. To analyse the wave you can make a video using a screen capture software such as Camtasia or stop the motion and analyse using your ruler or an onscreen ruler. Investigate the different harmonics by varying...
