Abstract
The translational dispersion of sound in gases is discussed from the standpoint of kinetic theory. An explicit relation is derived for the variation of sound velocity with frequency in monatomic gases; this relation is: V = V0(1 – 5.4l2/λ2), where l is the mean free path, and λ the wave-length. The possibility of experimental observation of translational dispersion is briefly discussed.
