The differentiation between plasma dynamics governed by collisional transport and collective processes has gained attention in recent studies. This paper aims to numerically evaluate the collisional damping rates of Langmuir and ion-acoustic waves as derived from a unified kinetic theory that integrates both dynamics and collisional effects. Employing a Maxwellian velocity distribution for plasma particles, the study applies rigorous formalism to obtain collisional damping rates, contrasting them with conventional heuristic approaches. Notably, the findings reveal that these accurate damping rates are significantly lower than those predicted by traditional formulas, indicating that prior methodologies may overestimate the role of collisional processes in attenuation of plasma waves. This research contributes to a better understanding of plasma wave behavior across various scenarios, including laboratory settings and astrophysical contexts.
