This diagram shows different regions of the ultraviolet (UV) portion of the electromagnetic spectrum. There are several named regions of the UV spectrum corresponding to different wavelengths of the electromagnetic waves. Some of the regions overlap. Short wavelengths correspond to higher frequencies and higher energies, while longer waves oscillate at lower frequencies and carry less energy. Visible light and the start of the infrared (IR) spectrum are shown for comparison.
