Electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength.
Depending on the wavelength of a particular EMR source, it may be visible to the human eye (in the light spectrum). While we provide more detailed definitions of types of EMR in this article, roughly EMR is divided according to its wavelength (in order of decreasing wavelength) into electric...
