== History ==

 

Besides [[astrophysics]], Ångström studied [[heat]] transfer, [[terrestrial magnetism]], and the [[aurora borealis]], which was so prominent for him in his northern skies. He created a spectrum chart of [[solar radiation]] that expresses the [[length]] of [[electromagnetic radiation]] in the [[electromagnetic spectrum]] on the order of multiples of one ten-millionth of a [[millimetre]], or 1{{e|−10}} [[metre]]s. This unit of [[length]] became known as the ångström, Å.

 

Today, the use of the Ångstrom as a unit is less popular and the nanometre (nm) is often used instead (a metre to the power minus 9 or m -9), the visual region in this case being 400 to 700 nm
