A Computational Visualization of Two-Dimensional Wave Interference Using Python

Abstract

Wave interference is a fundamental phenomenon in classical physics arising from the principle of superposition. While the underlying mathematics is well established, conceptual understanding often remains abstract for students and early researchers. In this work, a two-dimensional computational model of wave interference is developed using Python. By simulating two coherent point sources emitting harmonic waves, clear regions of constructive and destructive interference are visualized through intensity patterns. The model demonstrates how path difference and phase relationships give rise to interference fringes analogous to those observed in classical optics experiments such as Young’s double-slit experiment. This study highlights the effectiveness of computational visualization as a pedagogical and analytical tool in physics.
