Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz .
Purple and blue are related to nitrogen, with purple lights appearing higher than 60 miles above the ground while blue hues glow below this threshold. Green, red and purple aurora over Mefjord in ...
