Answer:
1. Twanging sound
2. Back and forth
3. producing a higher pitch.
Explanation:
- 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
- The shorter bands will vibrate faster, producing a higher pitch.
- In general, the thicker the rubber band, the lower the pitch and the longer the rubber band, the lower the pitch. The speed of sound is slower at higher altitudes because the air temperature is lower. The greater the amplitude, the louder the sound. It is your perception of the energy of a sound.
