Question

Quizplus · Accepted Answer

Electromagnetic radiation is composed of interacting electrical and magnetic fields, as described by Maxwell's equations. It does not have to be visible (e.g. radio waves, X-rays), does not always radiate out in confined planes (e.g. spherical wavefronts), and can also exhibit particle-like behavior (e.g. photons).
