For a system in thermal equilibrium use Boltzmann's relationship to calculate the ratio of the number of atoms in energy states E1 and E2 if the wavelength of light produced by a transition between the two is 633nm at 300K. If the temperature is reduced to 200K what is the new ratio? Explain the significance of the calculated ratios above in the production of laser light.

a) The use of spectrophotometry to scan a solution that contains an organic dye will show which wavelengths in the visible spectrum that organic dye most strongly absorbs. Then, using the relationship between energy and wavelength that you learned in Chapter 6, E = hc/λ you could convert each wavelength to its corresponding energy. If you found that an organic dye compound strongly absorbs at 566 nm , what is the energy that corresponds to the excitation of an electron...
