Your boss has asked you to buy a new grating for your grating monochrometer. She has told you that you need to measure peak intensities at wavelengths of 501.1 nm and 501.3 nm. Assume slit widths of 0.3 nm and a grating that must be 5 cm long. What groove spacing should you choose? Does this grating spacing seem physically possible?
