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.
Electromagnetic waves are formed by the vibrations of electric and magnetic fields. These fields are perpendicular to one another in the direction the wave is traveling. Once formed, this energy travels at the speed of light until further interaction with matter.hese changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
