Wave processes propagating in a medium of collisional and viscous quark-gluon plasma (QGP) are comprehensively analyzed in the paper. To investigate various optical properties of the medium, the longitudinal and transverse dielectric functions of the quark-gluon plasma are taken to study. The calculations of perturbations in these dielectric functions facilitate the derivation of dispersion relations for wave propagation within such media. Through extensive further analysis, the phase and group velocities were calculated for the considered models. The resulting graphs for phase and group velocity distinctly illustrate the dissipative properties inherent in the medium, revealing how these properties influence the propagation speed of both the wave phase and the wave packet of environmental disturbances. This article provides an in-depth analysis of the obtained results, discussing the possible behavior of waves across different models of quark-gluon plasma media. The study concludes by highlighting the achievements and contributions of this research, emphasizing its importance in advancing the understanding of wave dynamics in such extreme states of matter.
