Abstract：

Based on Python libraries such as Matplotlib, Numpy, and Py Qt5, this paper designs and develops a simulation platform for the Young's double-slit interference and doubleslit diffraction experiments. The simulation platform can dynamically display the optical paths, spectra, and intensity variations corresponding to double-slit interference and diffraction in real time by adjusting experimental parameters such as wavelength, slit width, slit separation, screen distance, and medium refractive index. Additionally, the double-slit interference project discusses the color spectrum formed by trichromatic light as the light source, while the double-slit diffraction project features a discussion on the missing-order phenomenon. The platform also embeds animations of the double-slit interference optical path principle made with Geo Gebra and a 3D animation of the double-slit diffraction experiment made with Solid Works, vividly illustrating the mechanisms of double-slit interference and the experimental process of double-slit diffraction. This simulation platform helps students understand abstract optical theories and formulas, analyze the differences and connections between doubleslit interference and diffraction, and serves as an effective auxiliary tool for both theoretical and experimental teaching in wave optics.
