Hi Ivan, The fly, and every part of the line, is part of the wave. I know that doesn't help answer your question, but the question does not really make sense. This might help: Imagine you have applied some tape directly to the fly line 30' back from the leader. You make a cast and put a mend in the ...

The wave carries the boats up and down. If you were able to freeze the water instantly and the wave was under the boat at the time, the boat would have been left higher up, even though the direction of wave propagation was horizontal. Here we have vertical wave propagation and the fly is carried hor...

Well for me I think it stops becoming a transverse wave the moment it becomes untethered. Ie it stops moving vertically (in this case) which would be the transverse direction. Okay, so it's the "moving vertically" that's the problem now, even though the wave still moving the same direction relative...

As I've been saying all along in this thread, I see it as a transverse wave. I make no distinction between "a loop" and "a transverse wave", so it became a loop as soon as the rod tip stopped moving to the left of screen (i.e. well before the tether was released.) Why is there a difference for you? ...

But once the chain is near my finger I can’t get it to wiggle outwards. A transverse wave by its very nature should propagate at 90 degrees away from my finger’s direction. Despite being nimble I still can’t accomplish this feat. Which direction is 90 degrees from the line you trace on the floor wi...

Put the line on the floor and a transverse wave should propagate at 90 degrees to the applied motion and it doesn’t.

Maybe that's because you put it on the floor?

I suppose another difference when fly casting is that the 1/2 wave length decreases in size as the loop unrolls, usually disappearing to zero? I don't understand this at all. The half wave length? How is that measured? Whereas with tethered string one would expect the transverse wave to propagate a...

Just so we are discussing the same things. 8B7B5C3D-D372-4B56-99F4-2C6D7FBBEFDF.jpeg For you the height of the loop is half the wave length I assume. What is the amplitude? Back and forward casts combined, or just one of them? Cheers, Paul This is where things get complicated because our string is ...

Are you saying that the flycast is only a transverse wave when affected by gravity?

No. I'm saying it's a transverse wave.

Why were you taking it out of the equation? Are you heading to the space station soon?
