The electromagnetic spectrum is the distribution of electromagnetic radiation according to energy or frequency or wavelength:
| Type | Wavelength (m) | Frequency (Hz) | Energy (eV)* |
|---|---|---|---|
| Electricity | 5 105 | 50 - 60 | |
| Long wave, television | 105 - 102 | < 3 109 | |
| Short wave, radio | 102 - 10-1 | 108 - 3 109 | < 10-5 |
| Microwaves | 10-1 - 10-3 | 3 109 - 3 1012 | 10-5 - 10-2 |
| Infrared light | 10-3 - 7 10-7 | 3 1012 - 3 1014 | 10-2 - 2 |
| Visible light | 7 10-7 - 4 10-7 | 4.3 1014 - 7.5 1014 | 2 - 3 |
| Ultraviolet light | 4 10-7 - 10-9 | 7.5 1014 - 3 1017 | 3 - 103 |
| X-rays | 10-9 - 10-11 | 3 1017 - 3 1019 | 103 - 105 |
| Gamma rays | 10-11 - 10-13 | 3 1019 - 1021 | > 105 |
| Cosmic rays | 10-13 - 10-20 | 1021 - 1025 |
* eV = electron-volts
