I was wondering how exactly sound waves are produced by a skipping rope. Specifically a plastic one, but I think it should occur in all materials.
There are two possible explanations I can think of:
- The rope travels through the air fast enough, to push the air molecules out of the way, thereby creating a compression wave. And another one when the molecules slam together behind the rope.
- The friction of the rope with the air creates the sound (how?).
Are these perhaps even the same? I'm not sure about how I'd go about exploring the validity of these hypotheses.
