A hydrogen discharge tube is used to illuminate a 10,000-line/cm diffraction grating. The grating produces first-order maxima at 24.2◦, 25.7◦, 29.1◦, and 41.0◦. a) Calculate the wavelength corresponding to each angle. b) Determine the angles for the wavelengths in (a) if they are produced instead by a 5,000 line/cm grating. (c) Find the location of the second-order maxima for these wavelengths and new grating. (d) Qualitatively discuss how the grating’s line density is related to the location and separation of the fringes.
