these are the only graphs

Wate 1 and 2 Graph B Grpah E Graph C Graph D 1. Based on your graphs, how does the choice of excitation wavelength appear alter a fluorescence spectrum? What about the effect of slit widths? What excitation and emission wavelengths would you use to determine the concentration of uranine in an unknown ethanol sample (i.e., what wavelengths appear provide the highest signal)? 2. How does the choice of emission wavelength appear to affect the shape or intensity of the excitation spectrum of uranine? 3. Discuss why uranine yield a relatively intense fluorescence spectra compared to ethanol (i.e., what is special about its molecular structure?)
