The complete range of all possible forms of light is called the electromagnetic spectrum, so-named because light carries both electric and magnetic fields. Recall that light behaves as both a particle and a wave; we say that light comes in particle-like "pieces" called photons, but that each photon is characterized by a wavelength and a frequency. Part AWe divide the electromagnetic spectrum into six major categories of light, listed below. Rank these forms of light from left to right in order of increasing wavelength. To rank items as equivalent, overlap them. Options: radio waves, infrared, visible light, ultraviolet, X-rays, gamma rays.
