Long wave goodbye
After making the pendulum wave a week or so ago I have been wondering about making a longitudinal version. The problem again was how to release the pendula at different times. I used a similar solution to the transverse wave with falling rods, my first attempt was to drop rods with different velocities. Each successive rod was slower than the last by 0.05ms-1 . This didn't work since as the rods went slower the time between them releasing the pendula was longer, so I decided to try different length rods with the same velocity. It worked quite well. After all this simulating I'd now like to do it for real, maybe I could organise a physics event at UWCRCN?
