What change if any does pencil make on the sound produce?
Answers
Explanation:
Just as the strings inside a piano create different sounds, so too will the rubber bands. When the rubber bands are plucked in order, from thinnest to thickest, the sound will gradually change from a high pitch to a low pitch. When a ruler "bridge" is added, it absorbs some of the vibrations. The length of the rubber band that is able to vibrate becomes shorter. The shorter bands will vibrate faster, producing a higher pitch. By moving the ruler "bridge" off the center point, one side of the rubber band becomes short and the other long. The longer length of the rubber band makes a low, long, heavy sound and vibrates at a slower rate of frequency. The shorter length of rubber band makes a high, short sound and vibrates at a faster rate or frequency.
