Simulation Process of Young's Interference Experiment

Young's interference is a famous experimental phenomenon in wave optics that demonstrates light's interference characteristics through double-slit experiments. In computer simulations, this process is typically presented through animations, which visually display bright and dark interference fringes resulting from light wave superposition.

The core of the simulation lies in calculating the superposition effect of two coherent light waves on the screen. When two light waves meet, their phase difference determines the distribution of interference patterns: positions with identical phases experience light intensity enhancement, forming bright fringes; positions with opposite phases undergo light intensity cancellation, creating dark fringes. The animation dynamically demonstrates the wave propagation and superposition process, helping to understand the physical nature of interference phenomena. In code implementation, this typically involves calculating wave equations using trigonometric functions and superposition principles, with real-time rendering of intensity distributions.

Such simulations often allow parameter adjustments, such as double-slit spacing, wavelength, or light source intensity, to observe changes in interference patterns under different conditions. This not only serves educational demonstrations but also has practical significance for preliminary analysis in optical experiments. From a programming perspective, key functions would include parameter input handling, wave equation computation using numpy arrays, and matplotlib-based visualization with interactive sliders for real-time parameter modification.
