The top view diagram at right illustrates two point sources, S_1 and S_2. On the diagram, indicate points for which the value of Delta D is largest and smallest. (Delta D is the difference in distances to the sources.) What are the largest and smallest values of Delta D for this situation? Explain your reasoning.
