You admire an art installation of a traveling wave on a string in a museum, which is created by a machine that oscillates the string. You take a picture of it, which is shown above. Taking more pictures of it, you observe that two photos look the same if they are taken exactly one second (or any integer multiple of one second, but not less) apart. The wave travels to the left. (m) NA- (a) is the graph in the figure above an example of a snapshot graph or a history graph? Explain. Snapshot History (b) What is the wave speed? m/s 10 400) (c) Provide the equation that expresses the displacement of a point having a coordinate z at time t, for this specific wave. (d) Sketch the displacement vs. time graph for this wave. Your graph should track the displacement at x = 0 m from t = 0s to t = 2 s. Make sure to label your plot. Is this graph a snapshot or history? (e) Suppose that the machine begins to oscillate twice as fast, but the tension remains unchanged. Sketch the new displacement as a function of position between 0 and 10 m (you can assume that the displacement at * = 0 m is still d = 1 m). Make sure to include axes labels and units.
