Current Attempt in Progress A diffraction grating with a width of 2.5 cm contains 1040 lines/cm across that width. For an incident wavelength of 600 nm, what is the smallest wavelength difference this grating can resolve in the second order? Number n Units v eTextbook and Media Calculate the minimum number of lines needed in a grating that will resolve a doublet of 590.0 and 590.3 nm in the second-order spectrum.
