Electromagnetic Spectrum

The full range of electromagnetic radiation in order of wavelength from longest to shortest, or frequency from lowest to highest (radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays). In terms of visible light, a light spectrum runs from red to blue. Astronomers scan as much of the electromagnetic spectrum as possible to learn about the nature of the universe and how it came to be.
