Abstract: Based on the Makie.jl and DifferentialEquations.jl libraries in the Julia language, we present a comprehensive interactive visualization of harmonic oscillation synthesis, forced vibration, and Fraunhofer diffraction from gratings, regular polygonal apertures, and circular apertures. The application of Julia language offers a novel tool for teaching and research, benefiting both instructors and students by enhancing educational outcomes and fostering student enthusiasm for learning.

Key words: Julia language, interactive visualization, college physics
