    The electromagnetic spectrum is a group of transverse waves that travel at the sped of light.

    They include, from smallest to largest. cosmic rays from outer space, gamma rays from radioactive materials, X-rays, ultraviolet, visible light, infrared. microwaves, radio waves, tv waves, electric waves.

    In a word: Light

    In more detail, the Electromagnetic Spectrum (or EM Spectrum), is made up of all forms of visible and invisible light from Gamma rays through X-rays, Ultra-Violet light, Visible light, Infra-red light, Microwaves and Radio waves. All of these rays travel at the speed of light and are distinguishable by their frequency and wavelength, I have ordered them from highest frequency to lowest. Note that it is a continuous spectrum with no hard and fast divisions between these types of EM Radiation, but are commonly broken down into those categories.
