My understanding is that the sound wave should travel through the open end since there is no barrier. The air particles in a sound wave are vibrating parallel to wave direction. At the open end, the air particles vibrating should cause the air particles just outside the pipe to also start oscillating resulting in a wave outside the tube. The open end cannot exert a force on the air particles just inside the pipe to cause a reflected wave unlike a closed end.Orodruin said:Why does this surprise you? It will be easier to address your question if you give the reasoning.
So, when pressure is low just inside the open end then air from outside would rush to inside the open end causing particles to move just inside the open end resulting in a wave traveling in opposite direction to original wave.Orodruin said:Consider this: At the open end, pressure is approximately constant. If there was just a wave towards the open end, there is no way that pressure could be maintained constant.
When a sound wave enters an open organ pipe, it travels down the length of the pipe and reflects off the open end. This reflection causes the sound wave to reverse its direction and travel back towards the source.
The frequency of the reflected sound wave in an open organ pipe is determined by the length of the pipe and the speed of sound in the medium. Longer pipes produce lower frequencies, while shorter pipes produce higher frequencies.
The diameter of an open organ pipe does not affect the reflection of sound waves. However, it does affect the resonance of the pipe, which can impact the overall sound produced by the pipe.
Yes, the reflection of sound waves in an open organ pipe can be manipulated by changing the length of the pipe. This can be done by opening or closing holes along the length of the pipe, which changes the effective length of the pipe and therefore the frequency of the reflected sound wave.
In a closed organ pipe, the sound wave reflects off the closed end of the pipe, resulting in a node (point of no vibration) at that end. In an open organ pipe, the sound wave reflects off the open end of the pipe, resulting in an antinode (point of maximum vibration) at that end. This difference in reflection affects the harmonics and overall sound produced by the pipe.
