I found that totally fascinating. I've always thought that the string vibrated primarily on its whole length, then at the half, quarter and other nodal points, but these are little bitty (and thus very high frequency partials.

Members Freeman Keller Posted July 19, 2011 Author Members Share Posted July 19, 2011 It's not a true picture of string vibration (this is, however). The iPhone video is an example of the rolling shutter effect. Your first link is more what I expected, and your explaination makes sense. The second vid is downright scary - maybe thats why they don't let you use your cell phone on an airplane, eh? I work with automatic control systems and there is a basic theorem that says that to recreate a waveform (which is what the video is trying to do) you must sample at least twice as fast as the highest frequency (or something like that) - I'm assuming that the iPhone samples way to slowly.
