## 概述

Interactive prism dispersion visualization - explore how white light separates into rainbow colors through refraction using Snell's law n₁sin(θ₁) = n₂sin(θ₂), Cauchy's dispersion equation n(λ) = A + B/λ², and deviation angle calculation δ = i + e - A. Features full 7-color spectrum (Red 700nm, Orange 620nm, Yellow 580nm, Green 530nm, Cyan 490nm, Blue 470nm, Violet 400nm) with wavelength-dependent refractive indices. Four materials: BK7 glass (n≈1.513-1.530), Flint glass (high dispersion), Diamond (very high dispersion), Water. Adjustable parameters: prism apex angle A (30°-90°, default 60°), incident angle i (0°-89°), prism size, and display options (normal lines, angle labels, ray labels, spectrum legend, animation). Four presets: Rainbow Colors (standard), Minimum Deviation (optimal angle), High Dispersion (flint glass), Custom Angle. Real-time statistics table showing incident angle, exit angle, deviation angle, and refractive index for each wavelength. Canvas-based 2D ray tracing with smooth light propagation animation, zoom/pan controls, glassy prism appearance, and spectrum bar. Educational content: Snell's law, Cauchy equation, wavelength-dependent refraction, normal dispersion, applications (spectroscopy, rainbows, optical instruments), and Newton's historical prism experiments. Multi-language support (zh, en, de, fr, es, ru, pt)
