hallo all,
while reading some info on soundwaves and overtones I found the following statement on wikipedia:
"The first overtone is the first allowed harmonic above the fundamental frequency (F1).
In the case of a system with two different ends (as in the case of a tube open at one end), the closed end is a node and the open end is an antinode. The first resonant frequency has only a quarter of a wave in the tube. This means that the first harmonic is characterized by a wavelength four times the length of the tube."
now I want to know why it is like this:
The first resonant frequency has only a quarter of a wave in the tube. This means that the first harmonic is characterized by a wavelength four times the length of the tube.
Why the 4 ?
how do they get that?

, come back, go down 
, and come back, to do one wavelength.
