frequency-length relationship

[jota]

I wanted to consult you on a technical aspect;

if the x-axis (x) we have the frequency of complete didgeridoo. Example 73 hz, 140Hz. And below 280 Hz ...
this is the question the drone or fundamental frequency is located in the first centimeters of the didgeridoo? and so subsequent? or am I wrong?
I wanted to know if this relationship is logic that is linking frequencies of the didgeridoo with its length.
otherwise please I would like to know how to interpret it thanks .juan . -
frequency is determined physically locatable in "any particular part of the didgeridoo by examples such fundamental place in the high media and other well?
I will extend to all the questions (I have little or no experience with forums), from and thanks for the suggestion.
the question was designed to determine whether to fine-tune the quality of the didgeridoo was convenient or not to leave any part of their degree wood thickness length. (but we inquired whether certain parts (you could get more or less associated with particular frequency).

I am no physicist, therefore I can't be of any help on that issue... but did you try to contact Frank Geipel ? He's a specialist who has done a considerable work on didgeridoo acoustic and even developed computer-assisted machines to carve instruments with very precise characteristics (BP, key of thr drone and toots...).
You should have a look on his instructive website and mail him for the questions that haven't got an answer.
