Sound Pressure in Longitudinal Waves
Description
Sound waves are longitudinal waves that create changing pressure in a medium. Their displacement amplitude can be modeled as a function of position and time. As one column of the medium moves, nearby columns also move. The difference between these successive displacements produces a pressure change compared with the surround...

Transcript
Pensemos en el sonido viajando a través de un medio. Las perturbaciones longitudinales crean una diferencia de presión entre sus columnas sucesivas, que luego sufren oscilaciones.
Considere un cilindro no perturbado del medio, con un área de sección transversal A a lo largo del eje x. Su desplazamiento longitudinal, dado...
