  "description": "The electromagnetic spectrum encompasses all types of EM radiation, ordered by wavelength/frequency: radio (longest), microwave, infrared, visible light (400-700nm), ultraviolet, X-ray, gamma ray (shortest). All travel at speed of light (c = 299,792,458 m/s). Maxwell's equations (1865) unified electricity, magnetism, and light.",
