1. The problem statement, all variables and given/known data Suppose we listen to the sound of a vibrating string with a pickup that is sensitive to the motion at a point 1/3 of the string's length from one end. Which statement is true? A.) We will be able to hear all of the modes except the third B.) We will not be able to hear the third mode or the sixth mode C.) None of the statements above are true D.) We will be able to hear only the 3rd and higher modes E.) We will only be able to hear the 3rd mode 2. Relevant equations None 3. The attempt at a solution I have made a mono-cord and measured frequency at different modes for this class. We have discussed that when you excite the fundamental, you also excite all modes above it. But when you select higher modes, you won't excite the modes below it. So I at first tried (D) but the answer was incorrect. Then I figured that maybe by "pickup that is sensitive" it meant that the pickup could only hear the point at 1/3, so figured they would here the 3rd and 6th and so I selected (C) but that also isn't correct. I think I must just be misunderstanding the question all together.
