electromagnetic radiation
electromagnetic radiation (EMR) The range in radiation extending from wavelengths of less than 10
−12m to more than 10
3m. In order of increasing wavelength are included cosmic ray photons, gamma rays, X-rays, ultraviolet radiation, visible light (violet to red), infrared radiation, microwaves, radio waves, and electric currents.
