- Light | Definition, Properties, Physics, Characteristics, Types . . .
Light is electromagnetic radiation that can be detected by the human eye Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 −11 metres to radio waves measured in metres
- Light - Electromagnetic, Wavelength, Spectrum | Britannica
In his formulation of electromagnetism, Maxwell described light as a propagating wave of electric and magnetic fields More generally, he predicted the existence of electromagnetic radiation: coupled electric and magnetic fields traveling as waves at a speed equal to the known speed of light
- Light and its properties | Britannica
In the mid-19th century, light was described by James Clerk Maxwell in terms of electromagnetic waves, but 20th-century physicists showed that it exhibits properties of particles as well; its carrier particle is the photon Light is the basis for the sense of sight and for the perception of colour See also optics; wave-particle duality
