b. Write a Python program using your function from part a) to plot the ratio of the scattered for angles from zero to 150 degrees. energy to input energy, Eout Ein Plot three lines on the same graph, showing the variation in scattered energy for the following three input energies: 17.4 keV, 174 keV, and 348 keV. Label and annotate your plot appropriately. Your program should export the plot as a .png file. Paste a copy of this plot into your answer. You do not need to include any other parts of the program or notebook. (4 Marks) c. The plot from part b) helps to understand how the outcome of the experiment depends on the energy of the incoming photons. Explain briefly (two or three short sentences) how you might change the design of the experiment based on this plot, and why. (2 Marks)
