electromagnetic spectrum

the range of frequencies and wavelengths associated with radiant energy.

e·lec·tro·mag·net·ic ra·di·a·tion

, electromagnetic spectrum (ĕ-lek'trō-mag-net'ik rā'dē-ā'shŭn, spek'trŭm)
Wavelike energy propagated through matter or space; varies widely in wavelength, frequency, photon energy, and properties; may be natural or artificial and includes radiowaves, microwaves, heat waves, visible light, ultraviolet light, x-rays, gamma rays, and cosmic radiation.

electromagnetic spectrum

The continuum of radiation, varying in frequency, and, correspondingly, wavelength, that includes, in order of decreasing frequency, cosmic ray photons, gamma rays, X rays, ultraviolet radiation, visible light, infrared radiation, microwaves, radio waves and heat.

electromagnetic spectrum

the entire range of wavelengths of electromagnetic radiation, most of which are not detectable by the human eye except in the visible spectrum from about 400–700 nm wavelength. Wavelengths shorter than the visible spectrum contain large quantities of energy which can be harmful to living material. See Fig. 141 . See X-RAY, GAMMA RADIATION, ULTRAVIOLET LIGHT.

electromagnetic spectrum (·lekˈ·trō·mag·neˑ·tik spekˑ·trm),

n the entire range of electromagnetic radiation that extends from the longest (radio waves) to the shortest (gamma radiation) wavelengths.
