The dispersion relation for waves propagating in a gas according to kinetic theory is studied. Collisions are described by means of the model proposed by \textit{P. L. Bhatnagar}, \textit{E. P. Gross} and \textit{M. Krook} (BGK) [Phys. Rev., II. Ser. 94, 511-525 (1954; Zbl 0055.236)]. New numerical results for shear and thermal waves are given. The high frequency behaviour of the solutions obtained through analytic continuation of the dispersion relation is discussed.
