A wave-form produced by simultaneous oscillation of electric and magnetic fields perpendicular to each other. The direction of propagation of the wave is perpendicular to the oscillations. The following waves, in order of increasing frequency and decreasing wavelength, are electromagnetic: radio, television, microwave, infrared, visible light, ultraviolet, x-rays, and gamma rays.
Waveforms characterized by alternating upper and lower peaks with a specific distance between each peak. These waves propagate at the speed of light, which is approximately 186,000 miles per second, and their frequency corresponds to the vibration rate represented by the wave peaks. X-rays are a type of electromagnetic waves, as explained by Maxwell’s Theory.
