What did you observe when you plucked each of the rubber bands and sounds is produced How then is sound produced?
Yes If we stretch a rubber band and when we strike it it will produce a vibrant sound . That sound is produced by vibrating that stretched band .
What do you hear when you plucked a rubber band?
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 sound of the rubber band instrument when pulled?
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.
Why do the students hear sounds when they pluck their rubber bands?
Vibrations move out in all directions as sound waves, moving the air backward and forward. These waves make your eardrums vibrate, and you hear a sound. When kids make this mini guitar box and pluck the rubber bands, they can see—and hear—how sound travels, and experiment with different kinds of sounds.
Are there any changes in the note when you plucked the stretched band?
Yes. there are changes in the note when you the stretched band plucked.
What happened when you stretched the band over the box?
A rubber band is an elastic material in nature. When stretched, it changes its shape and when the applied force is removed, it regains its original shape. That is why a rubber band changes its shape even though it is a solid.
How does sound affect energy?
Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. This makes them bump into more nearby air molecules. This “chain reaction” movement, called sound waves, keeps going until the molecules run out of energy.
Are there changes in the note when you plucked?
There are changes when we pluck the stretched band. Explanation: There are normally two states for a band. One is Normal state, where there is no external tensile force applied on it.
What if we could hear the sun?
If space were replaced with air and we could hear the Sun, it would be incredibly noisy – the output of the Sun is equivalent to 10 million keys, or notes, of a piano. Sound intensity decreases with distance, which means that the Sun would deliver a much smaller 125 decibels to the surface of our planet.
What do you think does the rubber band represent?
Rubber bands help us hold all sorts of things together. Some parents thought teenagers were wearing sex bands, or colorful bracelets that resembled rubber bands, to signify what sexual acts they were willing to do with others. But this was an urban legend, the colorful wrist-wear was just a fashion statement.
What factors affect the pitch and loudness of the sound?
The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.
What happens to the rubberband?
In nature, a rubber band is an elastic substance. It changes shape when extended and returns to its original shape when the applied force is withdrawn. That is why, after being a solid, a rubber band changes shape. Furthermore, if too much stress is applied, the rubber band will snap.
