begingroup I agree that, if there were any improvements made by using pulses or AC in hydrolysis, it couldn''t have anything to do with resonant frequency. Logically, since DC had no frequency, and it does break the bonds, it does so in a nonresonant way, therefore, it would appear pointless to attempt any kind of frequency modification.

resonance. The ear canal is similar to an organ pipe that is open at one end. When any sound enters a tube that is closed at one end and open at the other end the simplest standing wave that can form under these circumstances is onequarter wavelength long. The fundamental resonant frequency is the lowest frequency possible in the ear canal,

Tesla''s Earthquake Machine Method Every rigid object in existence has a natural structural resonance frequency, a frequency at which it, metaphorically speaking, wants to shake more than any other. If you vibrate an object at its resonant frequency, it will gradually shake more and more wildly, like a child on each swing being pushed higher and higher on each swing, until eventually it shakes itself to pieces.

If GHz were the resonant frequency of water molecules the microwaves would all be absorbed in the surface layer of a substance (liquid water or food) and so the interior of the food would not get cooked at all. The GHz is a kind of useful average frequency.

Every material (such as glass, steel, concrete) has a natural frequency at which it vibrates, called a resonant frequency. If you put energy into the substance at its resonant frequency, you will force it to vibrate or resonate (resonance is a forced vibration).

Sand is a good agent of dissipating vibrations of a wide frequency range into heat. Air will also dissipate vibrations, because no mechanical coupling is the best decoupling. This can be done by making a second box outside the cabinet with as little mechanical coupling to the inner cabinet as possible.
