The visible light spectrum is the term used for all of the wavelengths of light (colors) that can be seen with the human eye.  The sun produces wavelengths of visible light that humans and other organisms can use in order to see the world around them.


Light radiating from the sun is contained in packets of energy called photons.  Photons are absorbed when plants use light energy from the sun to produce food.
