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.
How does a rubber band make sound?
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. ... The shorter length causes the band to vibrate faster and produces a higher pitch.
How did the sound change when you stretched the rubber band?
When we change the size of the cup that the rubber band is stretched around, the rubber band may get tighter or looser . When it is tighter, it can only move a short distance back and forth, which makes a higher pitched sound.
Does the length of the rubber band affect the frequency pitch of the sound?
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. ... The shorter length causes the band to vibrate faster and produces a higher pitch.
Which rubber band produced a higher sound?
Thicker, heavier, and loosely stretched rubber bands will sound lower pitched, while thinner, lighter, tightly stretched rubber bands will sound higher.
Which nail produces the highest sound?
The pitch of the sound increases because pitch depends upon frequency . When nail is hammered it produces an increasing frequency which is equal to the vibrations per second. As the nail enters the wall, that part gets shorter and the frequency of the vibration increases. ... Hence the pitch increases.
What happened to the sound when you increase the tension What happen when you stretch it?
The more you stretch the band, the more tension it is under and the faster it vibrates up and down . The number of vibrations every second is called the frequency and this tells you exactly how high or low the note is.
How does size affect pitch?
Pitch is a way of talking about how “high” or “low” a sound is. When you hit a big drum, it makes a lower pitch than a smaller drum might . ... Drums with larger heads (drum surfaces) take longer to wobble back and forth, creating slower vibrations and a lower pitch.
Did each rubber band produce the same sound without the bridge in place?
The shorter length of rubber band makes a high, short sound and vibrates at a faster rate or frequency. 1. Does each rubber band produce the same sound without the bridge in place? ... No, the pitch of the sound changes from a high pitch to a low pitch .
What factors affect the pitch of a sound?
Pitch depends on the frequency of a sound wave . When you listen to music, you hear both high and low sounds. The characteristic of highness or lowness of a sound is called The frequency of a sound wave determines the pitch of the sound you hear.
Which string has the highest pitch?
The violin is the smallest and highest pitched member of the string family. The sound of the violin is high, bright, and sweet. There are more violins in the orchestra than any other instrument.
What happens when you plucked the elastic bands the first time?
What happens when you plucked the elastic bands the first time? Answer: 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.
Which part of the rubber band shorter side or longer side provides higher pitch?
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.
Which sound can harm the human ear?
Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
Does higher pitch mean louder sound?
Children will often mix up pitch and loudness believing that a higher pitched sound is a louder one . Higher pitched sounds produce waves which are closer together than for lower pitched sounds. ... A smaller triangle or cymbal will make a relatively higher pitch note.
What makes a sound louder?
Changing the amplitude of a sound wave changes its loudness or intensity. ... A string plucked with force has greater amplitude, and greater amplitude makes the sound louder when it reaches your ear. Volume depends on amplitude. Greater amplitude produces louder sounds.
