The electromagnetic spectrum has many types of light waves. It includes radio waves, microwaves, infrared light, visible light, ultraviolet, X-rays, and gamma rays. Each type of light has a different ...

Figure caption, Each region of the electromagnetic (EM) spectrum has a range of wavelengths associated with it. Radio waves have the longest wavelengths and gamma rays have the shortest wavelengths.

Sensitive magnetometers commonly detect oscillations with a period of 100 seconds and a wavelength of 18,600,000 miles. The origin of these waves is unknown, but they promise to be useful in ...
