Light is energy. Light is also an electromagnetic wave. Electromagnetic waves are named so because the consist of two waves. One part electric and the other magnetic. Most electromagnetic waves are the result of excited electrons surrounding the nuclei of atoms.
amount of energy a photon contains determines what type of light is emitted
The above chart is called the electromagnetic spectrum. In the center is the visible light spectrum.
