Sodium’s emission lines at 589.0 nm and 589.6 nm pass through a diffraction grating and form two m = +1 maxima on a viewing screen. For which situation would the spacing between the two lines increase? The intensity of the light is doubled. The grating is exchanged for one with twice the total number of lines. The maxima are viewed in second order. The grating is exchanged for one having fewer lines per millimeter

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?
