Sound Wave Vibratory Frequencies
Source Wikipedia:
For physics, sound is an oscillation (a movement in space) performed by particles (atoms and molecules) in a physical medium of propagation. In the case of sound that propagates in a fluid medium (typically in air), the oscillations are displacements of the particles, around the rest position and along the direction of propagation of the wave, caused by vibratory movements, coming from a given object, called source of the sound, which transmits its movement to the adjacent particles, thanks to the mechanical properties of the medium; the particles in turn, starting to oscillate, transmit the movement to the other nearby particles and these in turn to still others, causing a local variation of the pressure; in this way, a simple vibratory movement propagates mechanically, originating a sound wave (or acoustic wave), which is therefore a longitudinal wave (in the case of fluids). In the case of solids, sound waves can be both transverse and longitudinal.
In the video we will see some cases in history in which sound waves have been the protagonists. We will start from the fall of the walls of Jericho to get to the 1940s when the Tacoma Narrow bridge lived one of the most incredible experiences ever filmed in history.
