Light from a mercury vapor lamp is passed through a diffraction grating with 1000slits/mm set 1.00 meters from a screen. The visible wavelengths of the prominent spectral emission lines of mercury are purple (405 nm), blue (436 nm), blue- green (492 nm), greenish yellow (546 nm), yellow (579nm), orange (623 nm), and red (691 nm). Write only your wordumerical answer with no units with three significant digits. Mercury (Hg) a. What color is the closest fringe to the central maximum? b. How far, Ay, in meters is the first fringe from the central maximum? c. What is the angle, @, of the first fringe measured from the central maximum? d. What is the difference in the two angles between the first and the last fringe? A A A A
