What happens to the pitch of sound if you tie a long rubber band on large box and pull the rubber band?
The length of the rubber band that is able to vibrate becomes shorter. The shorter bands will vibrate faster, producing a higher pitch. The longer length of the rubber band makes a low, long, heavy sound and vibrates at a slower rate of frequency.
How do you describe the movement of the rubber band when plucked fast?
If you pluck a rubber band, the rubber band moving back and forth produces twanging sounds. Unless something vibrates , there can be no sound. Sound travels when a string vibrates, it makes molecules of gases in the air next to it vibrate. The molecules squeeze together, then spread apart.
What happens to the pitch of a rubber band when plucked if we change the thickness?
The thickness of the rubber band changed the tone of the sound you heard when you plucked it. The thinner strings on a guitar make a higher-pitch sound because they can vibrate more quickly than the thicker ones.
Are there differences in sound when you tighten or loosen the rubber band?
Different rubber bands will produce different resonant frequencies, depending on their thickness or width, and how tightly they are stretched. Thicker, heavier, and loosely stretched rubber bands will sound lower pitched, while thinner, lighter, tightly stretched rubber bands will sound higher.
How do you describe the movement of the rubber band?
They shake from side to side and bump into each other. Because of that motion, the molecules tend to spread out sideways; so they must “un-straighten,” curl up, kink, tangle. That makes them pull inward on the ends of the rubber band.
How does stretching the rubber band affects the pitch of the sound produced?
All objects have a natural resonant frequency at which they vibrate. When plucked, a stretched rubber band will vibrate at its resonant frequency. Thicker, heavier, and loosely stretched rubber bands will sound lower pitched, while thinner, lighter, tightly stretched rubber bands will sound higher.
