J 35. Example 32.2. Consider a grating spectrometer where the spac- ing d between lines is large enough compared with the wave- length of light that you can apply the small-angle approximation sin 0-0 in Equation 32.1a. Find an expression for the line spac- ing d required for a given (small) angular separation A0 between spectral lines with wavelengths 1, and 12, when observed in first order.
