<p>Dispersion, nonlinearity, and waves-wave interactions are some of the important aspects of two-dimensional wave behaviour that are captured by the mathematical model known as the ion sound and Langmuir wave system. This study uses the truncated Painlevé technique to examine the (1+1) dimensional integrable ion Sound and Langmuir wave system. Various localised solutions, such as rogue or irregular waves, dromion-pair, and dromions can be produced via applying random functions to the findings. The collisional interaction of these solutions are produced, investigated, and visually displayed as a result of selecting suitable starting values for the arbitrary functions. We discover that dromions interact inelastically, exchanging both energy and phase, but rogue waves are inherently erratic. These findings advance our understanding of complex wave dynamics and have important implications for the study of non-linear occurrences in a variety of disciplines such as physical mechanisms, fluid dynamics, oceanography and nonlinear optics. It’s crucial to remember that all computations and visualisations are generated and their reliability and accuracy verified using Mathematica software. All things taken into account this work enhances our knowledge of complexities nonlinear systems and how their behaviour is influenced by their initial conditions. The study’s findings will aid in our comprehension of how waves behave in higher dimensional controlling models.</p>
