## 概述

Interactive electromagnetic spectrum visualization from radio waves to gamma rays, showing wavelength, frequency, and energy relationships across all seven major bands. Features fundamental formulas: c = λf (wave equation), E = hf (photon energy), with constants c = 2.998×10⁸ m/s (speed of light) and h = 6.626×10⁻³⁴ J·s (Planck constant). Real-time visualization includes: (1) Electromagnetic spectrum chart displaying seven bands (radio waves: 10³-10¹¹ Hz, 10⁵-10⁻³ m; microwaves: 10⁸-10¹² Hz, 1-10⁻⁴ m; infrared: 10¹¹-10¹⁴ Hz, 10⁻³-10⁻⁷ m; visible light: 4.3×10¹⁴-7.5×10¹⁴ Hz, 700-400 nm; ultraviolet: 7.5×10¹⁴-3×10¹⁶ Hz, 400-10 nm; X-rays: 3×10¹⁶-3×10¹⁹ Hz, 10-10⁻¹¹ m; gamma rays: 3×10¹⁹-3×10²² Hz, 10⁻¹¹-10⁻¹⁴ m) with color-coded regions and logarithmic wavelength/frequency scales; (2) Animated wave visualization showing sine waves with different wavelengths and frequencies for each band, with wavelength λ and amplitude A indicators; (3) Photon energy bar chart displaying E = hf in electron volts (eV) for each band, from 10⁻⁶ eV (radio) to 10⁸ eV (gamma). Interactive band selection displays detailed information: frequency range, wavelength range, photon energy, and practical applications (broadcasting, Wi-Fi, radar, microwave ovens, thermal imaging, night vision, lighting, photography, lasers, sterilization, medical imaging, security, astronomy, radiation therapy, nuclear medicine). Adjustable parameters: animation speed (0.1-3.0x), wave amplitude (0.5-2.0), band selection (radio/microwave/infrared/visible/ultraviolet/X-ray/gamma), view options (show/hide wavelength axis, frequency axis, energy scale, application labels, grid, labels), logarithmic/linear scale toggle. Educational content covers electromagnetic wave properties (transverse waves, perpendicular E and B fields, vacuum propagation at c, energy-frequency relationship), seven band characteristics and applications, safety considerations (non-ionizing vs ionizing radiation, thermal effects, DNA damage, exposure limits). Multi-language support (zh, en, de, fr, es, pt, ru).
