9. A diffraction grating is placed 1.00 m from a viewing screen. Light from a hydrogen lamp is passed through the grating, and the 656-nm-wavelength emission line in the hydrogen spectrum is seen 60.0 cm to one side of the center. Then the hydrogen lamp is replaced with a mercury lamp. a. Where does the 546-nm-wavelength emission line in the mercury spectrum fall on the screen? b. A spectral line is seen on the screen 36.4 cm away from the center. What is the wavelength?
