4. You need to achieve a baseline spectral resolution of 0.05 nm in an experiment using a 0.75 meter monochromator with a 1450 groove/mm grating blazed at 223. Under optimal conditions for rst order diffraction, what slit width is required (assuming entrance slit width and exit slit width are equal and large)? If you needed to satisfy the Rayleigh criterion rather than achieving baseline resolution, would the slit widths need to be narrower or could they be wider
