- Light - Wikipedia
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye [1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz

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 What is the speed of light?

Simply stated, light is nature's way of transferring energy through space We can complicate it by talking about interacting electric and magnetic fields, quantum mechanics, and all of that, but just remember--light is energy Light travels very rapidly, but it does have a finite velocity

Light, of course, is more than color: it is energy, which travels at incredible speeds throughout the universe From prehistoric times, humans harnessed light's power through fire, and later, through the invention of illumination devices such as candles and gas lamps
