That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Sorry, but you've got that exactly backwards. And regardless, even if propagating through a dispersive medium, the attenuation and absorption of sound are different processes to dispersion, so the fact remains that low frequency sound is less attenuated and less absorbed. Dispersion in particular means the crests of a sound wave will travel slightly faster than the troughs, resulting in waveform steepening (i.e. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. As a rule sound travels slowest through gases, faster through liquids, and fastest through solids. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.
