Tube model

[Yubin Z]

I am still a little bit confused about the tube model. Does it mean that the wave that gets the best resonation is one that its amplitude reaches the highest level when it leaves the tube? If so, why is that?

When you say “the wave that gets the best resonation” you are referring to a standing wave. The wavelength of this standing wave will be related to the length of the tube.

The waves are standing within the tube. This means that a pattern is set up within the tube, caused by the back-and-forth propagation of sound waves that re-enforce one another. These waves so do not “leave” the tube as such. Rather, the standing wave transmits energy to the air beyond the tube, which then propagates to the listener’s ears.
