1. The problem statement, all variables and given/known data A wave is sent along a long spring by moving the left end rapidly to the right and keeping it there. The ﬁgure shows the wave pulse at QR - part RS of the long spring is as yet undisturbed.Which of the graphs correctly shows the relation between the original position x of each point of the spring and the corresponding displacement ∆x of that point (Displacements to the right are positive.) 2. Relevant equations - 3. The attempt at a solution I think that it is #3 because the displacement at the begining is 0 correct? Also, the wave part is moving right which means it was displaceed at a positive. Also the end has not been disturbed yet so its diplacement is 0. Is all this correct. if it isn't, could you help me understand it? If the above was confusing to understand i apologize. Thanks in advance for the help!!!!!!!
