Bookmark or Share- Electromagnetic spectrum | Definition, Diagram, & Useselectromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies.
- Electromagnetic spectrum - WikipediaThe electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band.
- Wavelength - WikipediaThe wavelength (or alternatively wavenumber or wave vector) is a characterization of the wave in space, that is functionally related to its frequency, as constrained by the physics of the system. Sinusoids are the simplest traveling wave solutions, and more complex solutions can be built up by superposition.
- Wavelength | Definition, Formula, & Symbol | BritannicaWavelength, distance between corresponding points of two consecutive waves. “Corresponding points” refers to two points or particles in the same phase—i.e., points that have completed identical fractions of their periodic motion.
- Explainer: Understanding waves and wavelengths - Science News ExploresFor light in the electromagnetic spectrum, wavelengths can range from very long (kilometers-long for radio waves) to very small (a millionth of a millionth of a meter for gamma rays). The ruler shows how long these electromagnetic waves are in meters or fractions of a meter.
