What kind of node occurs at the open end of a resonant tube?

Sep 24th, 2014

The answer is An antinode occurs at the open end of a resonant tube.

Why do we have anti-nodes at the open end of a tube? Waves can be reflected, not only at the closed end of a tube, but also at the open end of a tube. Reflection occurs at the open end of a tube as a consequence of a phenomenon called radiation impedance, which occurs when a tube suddenly opens into a much larger space. Movement of air particles is not inhibited as it is at the closed end of the tube and so wave reflection occurs without inversion and anti-nodes are created at the open end.

However At the open end of a closed pipe; however,both nodes and antinodes are possible to form depending on the wavelength of the sound waves as well as the pipe's length.

The open end provides the conditions for an antinode, but the actual antinode has been found to occur outside the tube at a distance of about 0.6 r from the end, where r is the tube radius.
