a.) Sketch on the axes below with a solid curve (- ) below the SHAPE of a small angle X-ray scattering curve that would be seen for a dilute solution of Gaussian polymer chains. Both axes are linear. b.) Increase the volume fraction of polymer in the solution by a large amount. Sketch on the axes with a dashed curve-(----. ) the SHAPE of the scattering curve that would be seen. Ignore shifts in intensity up or down due to concentration differences. Show the relative shapes of the two curves. If the shapes are different, explain why. d.) Sketch the basic experimental setup for a SAXS experiment that can collect data for a range of q values simultaneously. Label all the parts
