When metallic sodium is dissolved in liquid sodium chloride, electrons are released into the liquid. these dissolved electrons absorb light with a wavelength near 800 nm. suppose we treat the positive ions surrounding an electron crudely as defining a three-d cubic box of edge l, and we assume that the absorbed light excites the electron from its ground state to the first excited state. calclulate the edge of length l.
