Considering the definition of speed and propagation of sound, sound is a sequence of waves of pressure which propagates through compressible media and depends on the characteristics of the medium in which the propagation occurs.
Definition of speed and propagation of sound
Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.
That is, sound is a longitudinal wave, mechanical (does not travel in a vacuum) and propagates in all directions, so that the wave front is spherical.
Propagation of sound involves energy transport without matter transport, in the form of mechanical waves.
The speed of propagation of a sound wave depends on the characteristics of the medium in which the propagation occurs and not on the characteristics of the wave or the force that generates it. The speed of propagation of sound waves is also known as the speed of sound.
Summary
In summary, sound is a sequence of waves of pressure which propagates through compressible media and depends on the characteristics of the medium in which the propagation occurs.
