The golden sunlight streaming through my window is itself nothing more than a welding of electric and magnetic fields. Indeed, everything from X-ray machines, ultraviolet tanning beds, infrared night-vision cameras, and microwave ovens to radar, radio and TV broadcasts, and the ultimate expression of modern life, this free Wi-Fi hotspot I’ve hopped onto with my laptop, are all based on varying forms of light. The electromagnetic spectrum is a broad swath of waves with different frequencies of vibration of the coupled electric and magnetic fields, stretching from dangerous energetic gamma radiation to long-wave radio, but all propagating at the speed of light. ~ Page 221
