When viewing a plucked guitar string; the string appears to have a square wave?

Question

This is looking across the neck, and under incandescant light

Answer 1

i usully see it with mine aswel but you know when the wave move it moves in both directions and make a stand wave wich has a still point and a high displace point and in the guitar u'll see a wave with crecentic multiple waves and if you see rectangle then its the illution caused by light!!! >>>>>

Answer 2

The string DOES have a standing wave, but it is sinusoidal. Keep in mind that the string moves the slowest at the peak of the wave, so perhaps it is the slow response of your eye that makes it appear as a square wave.

I need to go take a look at this on my guitar.

Answer 3

hey, that could or could no longer be a subject. The string vibrates so the tone isn't consistent. in case you play with a heavy hand or an aggressive sort, you will get tones that are actually not as sparkling as in case you play with a lighter touch. some persons like that; others do no longer. in case you progression your finger with which you depress the string you could create a vibrato result. you could properly be shifting your finger some or no longer protecting a persevering with rigidity on the string. Vibrato isn't unavoidably a bad component. it is an result one learns to apply to accessory notes or boost their length. you could properly be listening to the different strings vibrating per the string you performed. The sound waves will cause them to vibrate. to envision this, mute (silence) the adjoining strings once you pluck those 2 strings. Later

Answer 4

Actually, the wave is sinusoidal. If you pluck the low E string as hard as you can, you will see quite clearly that it takes a sinusoidal shape to begin with. It will very quickly diminish in amplitude to a small sinusoidal shape that gives the impression of a rectangle. But ask yourself this - how can it be rectangular if you know that the ends can not move? Trust me, it is always sinusoidal in shape.

You should see the string strongest at its edges with an apparent gap in the middle - this is due to the string moving fastest in the middle of its oscillation. This is not a rectangle though.

Answer 5

It's an optical illusion because of light reflected off the frets.
