a wave propagated at the speed of light by the periodic variations of electric and magnetic fields. electromagnetic wave. A wave of energy consisting of oscillating electric and magnetic fields. Radio waves, light waves, and x-rays are electromagnetic waves.
Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vacuum. The oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The wavefront of electromagnetic waves emitted from a point source (such as a lightbulb) is a sphere.
