Sutichasqa ångströmmi [[Suysya|suysya llaqta]] [[pachaykamay|pachaykamaq]] [[Anders Jonas Ångström]]manta ([[1814]] watamanta - [[1874]] watakama) karan, [[ispiktruskupiya]]p huk tiksiqninsi.
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.
From 1927 to 1960, the ångström was a secondary unit of length for use in spectroscopy, defined separately from the metre, which was still defined based on the length of a bar of metal held in Paris. In 1960, the metre itself was redefined in spectroscopic terms, thus aligning the ångström as a submultiple of the metre.
The average visual acuity of a human being is from about 4,000 Ångstroms (violet) to 7,000 Ångstroms (deep red). There
are 10,000 Ångstroms in a micrometre (commonly called a 'micron', abbreviated μm, of which there are 1 million to a metre).
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
