@oldhvymec it’s EM radiation at that frequency/wavelength, not sound. Nothing to hear and outside the frequency range your eyes can detect so you will never see it either. https://sites.google.com/a/coe.edu/principles-of-structural-chemistry/relationship-between-light-and... 7.83 Hz has a wavelength of about 38,000 kilometers which is WAAAY off to the right in this chart, well past EM wavelength of radio waves. |
