I hate to be repetitive, but what about my though experiment? a string with particles. I imagine if that if I lifted up the first particle at 1 mile and hour, the second particle wouldn't move up until it feels a force from the first particle which will happen when it become taut or tense...

But doesn't my thought experiment also apply to a rope? and if it does, isn't the speed of a wave in a rope always the same?

I'm speaking of the fact that the speed at a which a wave can travel in a particular medium is fixed. I'm specifically referencing a wave on a string like material. I also messed up by asking why amplitude can't make the wave travel faster when I should have asked why the frequency (or in my...

Why is the speed of waves in a medium fixed? I'm trying to conceptualize this, but I can't. I imagine a long piece of chain on the ground, of course made up on individual links. If I yanked on the first link by lifting it up, it wouldn't in act a force on the second link until it made...
