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?

How Light Works - HowStuffWorks
But what exactly is light? We catch glimpses of its nature when a sunbeam angles through a dust-filled room, when a rainbow appears after a storm or when a drinking straw in a glass of water looks disjointed.
What is Light and How Does it Work? - Electrician U
But what exactly is light, and how does it work? This article gets into the fascinating science of light, exploring the nature of photons, the mechanics of human vision, the color spectrum, various lighting technologies, and the invisible realms of ultraviolet (UV) light.
The Basics of Light - Johns Hopkins University
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 - Encyclopedia.com
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.
Light – Learn Physics
What is Light? Light is a type of energy that enables us to see with our eyes. Light travels from a source, like the sun or a light bulb, to our eyes, and to the surroundings. That is the reason we can see objects during daytime with the sunlight, or with a light bulb in the night.
What is light? A guide to waves, particles, colour and more
Is light a wave or a particle? How is it created? And why can’t humans see the whole spectrum of light? All your questions answered.
Light - Simple English Wikipedia, the free encyclopedia
Light is a form of electromagnetic radiation that shows properties of both waves and particles. It is a form of energy. Light also keeps the Earth warm. Light exists in tiny energy packets called photons. Each wave has a wavelength or frequency. The human eye sees each wavelength as a different color.
