Standing Waves

So this weekend I was playing with my guitar when I looked a little closer at the strings. Every time I plucked one it would create a wave. Not only that the wave had two nodes on each end and one anti-node in the middle. This standing wave has a base frequency of an E at 82.41 Hz. This is the frequency of nothing touching the surface and just a wave produced by plucking the string. By lightly touching the string at its bisector you can create a node there and produce its first harmonic frequency. You can actually repet this for 4 more hamonic frequencies on this string. All you have to do is go to a position with a node of a harmonic frequency and then touch it to create a node there. Instead of the string vibrating at a certain speed and increasing the speed you are imposing a node at certain points changing the length rather than the velocity.

Thanks for reading, Mark.
