Excerpt from A Modified Method for the Determination of Relative Wave-Lengths

While Young actually did compute from Newton's data not only the relative, but also the absolute wave-lengths for the sev eral Spectrum colors, we can hardly class these values as stand ards of wave-length and we may say that all spectroscopic standards established prior to Michelson's evaluation of three wave-lengths in terms of the meter, were derived from observa tions on diffraction spectra produced by the grating. Let us out line the fundamental principles oi the grating methods, consider ing the grating as -a particular type of interferometer. If we throw the grating data for the determination of relative wave lengths into the form of the fundamental equation (i) we have, in general, for any grating and any combination of wave-lengths and orders.
