At DC, electromagnetics consists of two distinct disciplines: electrostatics, concerned with electric fields; and magnetostatics, concerned with magnetic fields. At higher frequencies, electric and magnetic fields interact to form propagating waves. Waves having frequencies within certain ranges are given names based on how they manifest as physical phenomena.

This section describes some of the characteristics of the electromagnetic spectrum, including some of the conventional names given to electromagnetic waves over certain ranges of frequency.
