physics problem involving time graphs

[graceful thorn]

i dont understand what they mean by "the left diagram shows the pulses at t=0", its a time graph? so

i also have no clue what the pulses are even doing so if anyone could explain to me whats actually occuring that would be incredible tysm

like are we looking at a certain particle on the rope and then from t=0 theres no displacement and as time moves on it goes up then down? or what

I think the graph is a typo, because this would imply the grey pulse travels backwards in time.

I think the x-axis is supposed to be, like, the actual rope.

so a distance graph?

i see, thanks a lot, i was thinking that too
