Frequency range of infrasonic wave is
WebLightning generates sound waves across a wide range of frequencies, including infrasonic waves below 20 Hz. Source mechanism for these low frequency pulses is still area for debate. Infrasound pulses detected after rapid changes of electrostatic field during the thunderstorm activity were analyzed. The measurements were done by large aperture … WebAnswer (1 of 3): A sound wave is the oscillation of compression and rarification of the medium carrying the wave. It could be air, water, steel, or anything else compressible. The general formula is c = \sqrt{\frac{K_s}{\rho}} where K_s is the coefficient of stiffness and \rho is the density. ...
