Electromagnetic Spectrum or Frequency Spectrum

The electromagnetic spectrum or frequency spectrum is the range of all possible frequencies of electromagnetic radiation. The electromagnetic spectrum of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. We differentiate between the different frequencies and the associated wavelength.

The electromagnetic spectrum extends from low frequencies (long wavelength) used for electrical power distribution, to radio frequencies for radio, TV, cell phones, microwave ovens and wireless networks through to short wavelength high gamma radiation at the opposite end of the frequency spectrum.
