What is electromagnetic radiation?

Electromagnetic radiation is the propagation of energy through space or matter via oscillating electric and magnetic fields that form waves. These waves can travel through a vacuum, so no medium is required, and the energy is carried by photons, which have no rest mass and move at the speed of light. This description captures why this type of radiation is described as wavelike energy traveling through space or matter. It’s not a static field, and it doesn’t require a material medium, unlike mechanical waves.
