Question

Whenever a musician plays a guitar, they pluck one of the guitar strings to produce a standing wave in the string. Then pinch down on the string at the other end at the guitar in different places along the neck of the instrument. In doing so, by changing where they pinch the string, the same standing wave on that string can produce multiple different frequencies, and therefore multiple different notes. Using the knowledge you have learned about harmonic frequencies set up on strings, explain why simply changing where you pinch the string can change the frequency.

Answer 1

Answer:

It's due to the distance from either ends of strings origin...

Explanation:

As we know that waves behave moving in a flow from one side to another side and this gives a prospective of motion. Suppose a wave is pinched from the near one end of a guitar then due to the distortion created by the point of tie of strings the wave super imposes and moves with a velocity v and produces a wave frequency f. as we the pinching go down to the center the wave stabilizes itself to a stationary origin right at the center and the frequency then changes accordingly as moving down on the string.
