Question

A slinky is attached to a rod in a way that the end of the slinky may not move(e.g., it is welded in place). The waveform (pulse) shown below is travelling along the slinky at a particular time. The waveform is traveling to the right at 4m/s. What waveform must we add to the right of the rod to guarantee the fixed end boundary condition? How should the added waveform travel to guaranty the fixed end boundary condition? To the right at 2m/s. To the right at 4m/s. To the left at 2m/s. To the left at 4m/s
