Question

At some point in your life you may have had an opportunity to skip rope. If you have one rope, you can skip by yourself or you can include two friends, each friend holding one end of the rope with you skipping in the middle. In this instance your friends represent nodes, and you an antinode. Is it possible to skip rope with three friends, with two of you in the middle jumping at different times? Explain how two jumpers can be in the middle in such a way that only one person has to jump at a time. In your explanation, refer to the terms node, antinode, and frequency.
