= Acoustic dispersion
{wiki=Acoustic_dispersion}
Acoustic dispersion refers to the phenomenon where different frequencies of a sound wave travel at different speeds when propagating through a medium. This results in the spreading out of the sound wave over time, as each frequency component arrives at a different moment. In many materials, the speed of sound is frequency-dependent, meaning that high frequencies may travel faster or slower than low frequencies based on the properties of the medium, such as its density, elasticity, and temperature.
