Sodium doublet has lines of 589 nm and 589.59 nm in its spectrum

I got 999 for the resolving power required for a diffraction grating if these lines to be distinguished (not sure it is right please check).

99,500 lines of the diffraction grating must be illuminated in order to resolve the second order spectrum, please can you explain why this is?

    A diffraction grating is used in second order, to resolve the spectrum of the light emitted by a sodium lamp. The sodium light is known to contain a doublet (λ 1 589.00 nm and λ2-589.59 nm). The grating contains 500 lines per centimeter. What is the minimum size of the grating that must be illuminated by the collimated light in order to resolve the two spectral lines?

    The spectrum of sodium has two closely spaced lines, known as the sodium doublet, with wavelengths 589.0 nm and 589.6 nm. When sodium light is incident on a diffraction grating with 4,300 rulings/cm, the maxima corresponding to this doublet are separated by Δy = 4.80 mm when the screen is L = 1.70 m from the grating. What is the value of m in this situation?

    ASAP PLEASE The spacing of ruled lines on a diffraction grating is 1,845 nm. The grating is illuminated at normal incidence with a parallel beam of white light in the 395.5 nm to 700 nm wavelength band. The angular width of the gap between the first order spectrum and the second order spectrum is closest to (in degree):

    The hydrogen spectrum has a red line at 656 nm and a violet line at 434 nm. What angular separation between these two spectral lines is obtained with a diffraction grating that has 4014 lines/cm? (Assume that the light is incident normally on the grating.) 5.11 x first order separation Your incorrect answer may have resulted from roundoff error. Make sure you keep extra significant figures in intermediate steps of your calculation. 10.21 x second order By how many wavelengths...
