Electromagnetic spectrum
The electromagnetic spectrum is the continuous range of electromagnetic-wave frequencies and wavelengths. Increasing frequency corresponds to decreasing vacuum wavelength, from radio toward gamma-ray wavelengths. For example, infrared light has a longer wavelength and lower frequency than visible violet light.
