electromagnetic spectrum

n. The entire range of electromagnetic radiation, which includes, in order of increasing frequency and decreasing wavelength, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, x-rays, and gamma rays.

electromagnetic spectrum

n (General Physics) the complete range of electromagnetic radiation from the longest radio waves (wavelength 10⁵ metres) to the shortest gamma radiation (wavelength 10^–13 metre)

elec′tromagnet′ic spec′trum

n. the entire continuous spectrum of all forms of electromagnetic radiation, from gamma rays to long radio waves.

electromagnetic spectrumThe electromagnetic spectrum can be measured in frequencies or in wavelengths. This diagram measures wavelengths in meters, ranging from the longest wavelengths (radio waves) to the shortest (gamma rays). Visible light, which is a band of colors from red to violet, is the only portion of the spectrum that can be seen by the human eye.

electromagnetic spectrum

The entire range of electromagnetic radiation. At one end of the spectrum are gamma rays, which have the shortest wavelengths and high frequencies. At the other end are radio waves, which have the longest wavelengths and low frequencies. Visible light, with intermediate wavelengths and frequencies, is near the center of the spectrum.

electromagnetic spectrum

The range of frequencies of electromagnetic radiation from zero to infinity. It is divided into 26 alphabetically designated bands. See also electronic warfare.
