A hydrogen discharge tube is used to illuminate a 10,000-line/cmdiffraction grating. The grating produces ï¬rst-order maxima at24.2â—¦, 25.7â—¦, 29.1â—¦, and 41.0â—¦. a) Calculate the wavelengthcorresponding to each angle. b) Determine the angles for thewavelengths in (a) if they are produced instead by a 5,000 line/cmgrating. (c) Find the location of the second-order maxima for thesewavelengths and new grating. (d) Qualitatively discuss how thegrating’s line density is related to the location and separation ofthe fringes.
