electromagnetic energy
Photons in motion
Electromagnetic energy is energy carried by electromagnetic waves—oscillating electric and magnetic fields that travel through space.
This includes visible light, radio waves, microwaves, X-rays, and gamma rays.
All electromagnetic energy travels at the speed of light and requires no medium for propagation: The sun bathes Earth in electromagnetic energy.
