A guide to resources on electromagnetic waves, from radio to gamma - their use, danger and occurrence, compiled by your librarians.

Electromagnetic Spectrum

The electromagnetic spectrum is a band of energy frequencies from radio waves to gamma waves, from the very lowest frequencies to the highest possible frequencies.

The spectrum is arranged by the frequency of its waves, from the longest, lowest energy waves to the shortest, highest energy waves.
