Light, or visible light, is a very narrow range of electromagnetic radiation of a wavelength that is visible to the human eye (about 400â700 nm), or up to 380â750 nm. More broadly, physicists refer to light as electromagnetic radiation of all wavelengths, whether visible or not.he energy of particles of non-ionizing radiation is low, and instead of producing charged ions when passing through matter, non-ionizing electromagnetic radiation has only sufficient energy to change the rotational, vibrational or electronic valence configurations of molecules and atoms.
