||An emission instrument has a resolution of 0.1 nm. Would emission from calcium ion at 393.366 nm interfere with emission from neutral ruthenium at 393.176 nm? What assumptions have you made?
||For the Cu 324.7 nm emission line, would an instrument with 0.1 nm resolution reveal evidence of self-reversal and, if so, how?
||For the Cu 324.7 nm emission line, would an instrument with 0.001 nm resolution reveal evidence of self-reversal and, if so, how?
||Complete the grating selection for the echelle system discussed in "Plane grating, Crossed with prism or grating, Multiple detector" by going to a grating catalog, finding a combination of groove density and blaze angle that gives the desired dispersion and free spectral range, and then choosing a first-order cross-dispersion grating to provide the desired order separation.
