Bottle is just like a closed organ pipe. So stationary waves will be formed and hence sound is produced with a particular frequency
Because sound is caused by the vibration of air. When air is caused to vibrate by blowing across the bottle top sound is formed.
I think the pitch would be lower because the sound is really low when it is empty.
the gathers in the bottle and when its full it must come out and when both directions hit that makes the wliziling sound
you increase the pressure
Really?
The headjoint itself, the embouchure hole specifically (the part you blow into) is where the sound is actually produced. The pitch is changed by the length of the flute changing, by pressing keys (much like when you blow across a soda bottle. the less liquid in the bottle, the lower the pitch)
Because sound is caused by the vibration of air. When air is caused to vibrate by blowing across the bottle top sound is formed.
The sound produced when blowing into a conch shell is due to resonance. The shape of the shell acts as a natural amplifier, enhancing the sound of the vibrations created by your breath. This phenomenon is similar to blowing across the top of a bottle to produce a similar sound.
The sound on a flute is produced by blowing quite a lot of air over the hole on the mouthpiece. Flutes have an oval hole over which you must blow. But to do this you must have the right mouthshape, the shape used for spitting rice is appropriate. Then you blow lots of air over the hole. If you blow into the hole, no sound can be produced. But you must blow lots of air, because some of the air escapes when blowing across.
I think the pitch would be lower because the sound is really low when it is empty.
Wave length is smaller in high frequencies.. hence a higher pitched sound...Example, when you blow on the tip of a beer bottle, when its empty, the vibration travels all the way down the bottle and back up, hence a 'deeper' sound. the more you fill the bottle, the less room the vibrations have to move up and down the bottle, making the wave length much smaller, making the frequency higher, and the resulting sound higher pitched.
Because it sends vibrations through the bottle to make a sound
the gathers in the bottle and when its full it must come out and when both directions hit that makes the wliziling sound
Because the tube is hollow
