Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. All of these, known collectively as the electromagnetic spectrum, are fundamentally similar in that they move at 186,000 miles per second, the speed of light. The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. The shorter the wavelength of the radiation, the higher the energy(http://observe.arc.nasa.gov/nasa/education/reference/emspec/emspectrum.html).

By splitting up light into its constituent colors, a spectrum is the result.
