noun

mass nounPhysics

The range of wavelengths or frequencies over which electromagnetic radiation extends.

- The electromagnetic spectrum is composed of a range of radiation frequencies from radio waves to X-ray and gamma waves.
- The frequency range of the electromagnetic spectrum that is visible to the human eye (and which we refer to as ‘color’) is a very small region in the entire range of photon energies we have observed in nature.
- The electromagnetic spectrum has no theoretical limit at either end.
