Electromagnetic spectrum wikipedia. The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. Emr emr savvy. Emr travels at the speed of light and is invisible to humans. It is generally organized by frequency and wavelength. The frequency of emr refers to the number of times it repeats itself or cycles per second as hertz (hz).
