Hi Rich,
 
    In the experiment you're referring to, the  frequency doubles as the pipe 
is shortened by half, not lengthened. wavelength  is inversely proportional 
to frequency.
 
    In a TC, you can run at a multiple of  the fundamental frequency, but the 
transfer of useful energy will be  substantially (exponentially) less with 
each octave..

Hello  all,

The other day when i was at work, and thinking about my coil and  design
changes. A question came across my mind. In a TC system does  the primary
frequency have to be the first (primary) harmonic frequency.  This may be
a stupid and dumb question I thought at first as well ,but  then i began to
think more about it. And remembered a small project i did  in grade school
with tuning forks and harmonics

The expirement was  basic and im sure all of you already know all this
,but here is a little  recap of what i was thinking.

In a wind pipe when a tuning fork at 500  Hz is struck and placed at the
mouth of the pipe and the pipe is then  adjust in height to example 10
in the pipe will begin to hum when the pipe  hits a resonant freq of 500
Hz if you change the height the pipe will stop  humming. If the pipe is
then further raised to 20 in the pipe will begin to  hum at the
second harmonic but this time at twice the harmonic frequency so  1000 Hz
.. and so on and so forth.. does the same apply to a TC  system.. if a 125
kHz primary can be at resonance a 125 kHz secondary can  it also do the same
with a 250 kHz secondary. If it is possible a second  question i ask
would the second harmonic change coupling and energy  transfer
