My water post from metallic diaphragm speaker is missing... But basically, as I remember it,
From the post "A Shield" and "A \(\Psi\) Gun" both dated 27 May 2016,
\(f_{res}=0.061\cfrac{c}{a_{\psi}}\)
were a particle of size \(a_{\psi}\) is resonated at \(f_{res}\).
In the case of hydrogen, its calculated size is \(53\,pm\), with this
\(f_{res}=0.061\cfrac{299792458}{53\times 10^{-12}}=345.0\,PHz\)
where \(PHz=10^{15}\,Hz\)
Since frequencies at integer division of \(f_{res}\), such as \(345.0\,Hz\) (\(\div\,10^{15}\)) or \(34.50\,kHz\) (\(\div\,10^{13}\)) will also resonate hydrogen. Hydrogen gas spilts,
\(H_2\rightarrow2H\)
and reacts with oxygen
\(4H+O_2\rightarrow2H_2O\)
to give water.
With a speaker at the audio frequency of \(345\,Hz\) will become wet at the diaphragm, and a piezo attached to a glass or metallic surface vibrating at \(34.50\,kHz\) will pool water on its surface.
Now that I have this bit of information, what was it needed for?!
