A student will be performing analysis of water samples collected from the Lake Eymir to determine Fe concentration using a flame atomic absorption spectrometer (FAAS) equipped with Echellette-type of grating and Fe-Ge-Pt multielement Hollow Cathode Lamp (HCL) for which high-resolution emission spectrum is provided in the above spectrum. The monochromator of the instrument has a focal length of 100 cm and a collimating mirror with a diameter of 3.5 cm. The grove density of the monochromator is 2000 blaze/mm and 10.0 mm of the grating surface is illuminated. Consider the figures and the information given above and answer the following questions:
