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.

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.
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.
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 – 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? - Chromaviso
In short, light is a component of electromagnetic radiation that is visible to us humans. It can be described as tiny units of energy known as photons, which originate from a source of energy such as the sun.
