Why do we assume that an antinode is present at open end of a tube?
Can a node be possible at open end?
Thank you in advanced.

Open end of tube resonance is a phenomenon in which a standing wave is created in an open-ended tube, causing the air molecules inside the tube to vibrate at specific frequencies. This results in the production of sound, and the specific frequencies at which resonance occurs are known as the natural frequencies of the tube.
The length of the tube is directly proportional to the resonance frequency. This means that as the length of the tube increases, the resonance frequency also increases. This is because a longer tube allows for more wavelengths to fit inside, resulting in a higher frequency.
Antinodes are points in the standing wave where the amplitude of vibration is at its maximum, while nodes are points where the amplitude is at its minimum or zero. In an open-ended tube, there will always be an antinode at the open end, while nodes will be present at specific intervals along the length of the tube.
Yes, the type of tube can affect the resonance frequencies. For example, a tube with a larger diameter will have lower resonance frequencies compared to a tube with a smaller diameter. This is because the larger diameter allows for more air molecules to vibrate, resulting in a lower frequency.
Open end of tube resonance is used in various musical instruments, such as flutes and clarinets. By changing the length of the tube (by opening or closing holes), different natural frequencies can be produced, allowing for a range of notes to be played. The placement of the holes also determines the locations of nodes and antinodes, affecting the quality of sound produced.
