Later, the student uses the oscillator to create a single pulse with initial speed vo at at the left end of the string, as shown above. The student wants to quantify the observation that the pulse slows down on the right half of the string. The student comes up with the following equation relating the string’s diameter D at a given point on the string to the speed v of the pulse at that point: v=vo(Do/D) (c) Is the equation consistent with the observation that the pulse slows down on the right half of the string? ____Yes ____No (d) Using frame-by-frame analysis of video of the pulse, the student plots the speed v of the pulse as a function of the string diameter D, as shown below. Are the data in the graph consistent with the student’s equation above? ____Yes ____No
