Electromagnetic SpectrumThe electromagnetic spectrum describes the range of electromagnetic waves placed in order of increasing frequency. At one end of the spectrum are radio waves, which have a very low frequency and long wavelengths. At the other end of the spectrum are high-frequency, short wavelength gamma rays. All electromagnetic waves travel at the same speed--the speed of light. They differ in the amount of energy they transfer, called electromagnetic radiation. Lower-frequency waves like radio waves emit less electromagnetic radiation than do higher-frequency rays like gamma rays.
