We are all very aware that light is made up of electromagnetic particles that travel in waves. These waves emit different amounts of energy depending on the length of the wave. Shorter wavelengths emit higher amounts of energy, while longer wavelengths emit less energy.
Each wavelength is represented by a different color and is grouped into a certain category based on its range of wavelengths. These categories include gamma rays, x-rays, ultraviolet (UV) rays, visible light, infrared light, and radio waves. All of these groups combined make up the electromagnetic spectrum.
