Electromagnetic wave radiation, also known as electromagnetic radiation, is an electric field and a magnetic field that are oscillated in the same phase and perpendicular to each other to transmit energy and momentum in the form of waves in space. The direction of propagation is perpendicular to the plane formed by the electric field and the magnetic field.

The carrier of electromagnetic radiation is a photon, which does not need to rely on the medium to propagate, and the propagation speed in the vacuum is the speed of light. Electromagnetic radiation can be classified by frequency, from low frequencies to high frequencies, mainly including radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays.
