The monochromator for a new spectrophotometer must be able to resolve lines that areverfy close togetherat 631 nm What resolution is required for a diffraction grating to resolve wavelengths of 631.43 and 631.46 nm? (Give your answer to 5 Sig Figures it) With a resolution of 104. how close in nm is the closest line to 631.43 nm that can barely be resolved? (Give your answer to 1 Sig Figures iii) Calculate the second-order resolution of a grating that is 8.00 cm long and is ruled at 185 lines/mm. (Give your answer to 5 Sig Figures iv) Find the angular dispersion (Ap) in degree between light rays with wavelengths of 631.43 and 631.46 nm for 40th-order diffraction in = 40) and 4 = 10.00 (Give your answer to 3 Sig Figures
