9. Mercury atoms emit light at several wavelengths, see figure below. Light from a mercury lamp travels through a diffraction grating and is cast on a screen 50 cm away. The emission at wavelength 404.656 nm creates a first order bright fringe at 21.961 cm from the center maximum. What then is the wavelength of the bright fringe at a distance 34.991 cm from the center maximum. Note: the whole spectrum below is one mode or m. Mercury (Hg) 400...

The electronic absorption spectrum UI (Cr(NH3)6]3+ (aq) is shown in Figure 11.5. One of the observed peaks is centered at about 303 nm. 1.a. What is the approximate value of the wavelength for the two other peaks? Which one of these three peaks falls in the visible region of the electromagnetic spectrum? The wavelength at this peak is (Amax), and this transition accounts for the color of the complex ion in solution. The energy of the transition occurring at...
