    The show explained scientific concepts by means of simple experiments that anyone could replicate. In addition, hobbyists were given the opportunity to present their inventions; these included a pretzel-cutting machine and a foam-throwing machine. Each week, the show included some "crazy" experiments by Knoff-Hoff Professor Charlie (played by ...

    en.wikipedia.org/wiki/Microwave_auditory_effect

    In his experiments, the subjects were discovered to be able to hear appropriately pulsed microwave radiation, from a distance of a few inches to hundreds of feet from the transmitter. In Frey's tests, a repetition rate of 50 Hz was used, with pulse width between 10–70 microseconds.

    The sound comes from a standing wave whose wavelength is about twice the length of the tube, giving the fundamental frequency. Lord Rayleigh, in his book, gave the correct explanation of how the sound is stimulated. [7] The flow of air past the gauze is a combination of two motions.

  9. Kundt's tube - Wikipedia

    en.wikipedia.org/wiki/Kundt's_tube

    The sound generator is turned on and the piston is adjusted until the sound from the tube suddenly gets much louder. This indicates that the tube is at resonance. This means the length of the round-trip path of the sound waves, from one end of the tube to the other and back again, is a multiple of the wavelength λ of the sound waves. Therefore ...
