Using a High-Speed Camera to Measure the Speed of Sound
Schematic for the sound detector (taken from www.sparkfun.com/datasheets/BreakoutBoards/Amplified-Mic-v10.pdf). A fully assembled version is available on a circuit board for under $10 at www.sparkfun.com/commerce/product_info.php?products_id=8669.
The frames corresponding to a balloon rupture. The first frame is when the balloon was last fully inflated. The second frame is the first frame with signs of deformation. The third frame shows the change in the two frames.
First frame showing LED activation due to balloon rupture.
Distance from balloon to flasher plotted versus the average delay from balloon rupture to light emission. The horizontal error bars represent one frame of the video while the vertical error bars indicate the error associated with the diameter of the balloon and distance to the balloon.
Timing data collected from all trials.
