| Mar 17, 2016 at 3:43 | comment | added | rob♦ | @slebetman I mean specifically in the video linked by CuriousOne, which is using a second-generation clever trick. Here's a link to the middle of the video where you can see that different parts of the guitar neck are illuminated at different times to duplicate the "rolling shutter" illusion. An ordinary strobe light would illuminate the entire neck at once. | |

| Mar 16, 2016 at 18:10 | comment | added | rob♦ | @CuriousOne Actually the "stroboscopic" lighting is specifically designed to reproduce an artifact of the CMOS "rolling shutter" in most digital cameras by illuminating different parts of the strings at different times. I suspect that if you illuminated a vibrating guitar string with an ordinary strobe light whose frequency matched the fundamental or the harmonics for the string, you would see sinusoidal displacements. | |

| Mar 16, 2016 at 13:48 | comment | added | CuriousOne | Just to make this clear: one can oscillate a string at any frequency. It's not "quantized". The standing waves are just the eigenfrequencies that it carries out on its own and that have the least damping. When you "pluck" a string, you excite all kinds of modes and frequencies, not just the first mode or the first few modes. However, the higher modes decay quicker and they leave the fundamental ringing longer. Under stroboscopic lighting one can see that plucked strings are not harmonic: someecards.com/life/tech/… | |
