Electromagnetic wave
An electromagnetic wave is a wave composed of two components, an electric field and a magnetic field, and propagates to a light flux in space. Electromagnetic waves are transmitted through photons, and they are divided into radio waves, infrared rays, visible rays, ultraviolet rays, X-rays, and gamma rays along the wavelength. The light perceived in the human eye is visible light, and the light of various wavelengths, including visible light, is part of the electromagnetic wave.
