Phys.org / A 'seating chart' for atoms helps locate their positions in materials

If you think of a single atom as a grain of sand, then a wavelength of visible light—which is a thousand times larger than the atom's width—is comparable to an ocean wave. The light wave can dwarf an atom, missing it ...
