more sound in pipes :(

how is this image explained? Specifically, the high pressure wave that rebounds seems to be creating energy. How is a high pressure wave generated from a low pressure wave?

Second, I asked this earlier, answered myself, then realized my explanation did not explain open pipes, only closed pipes. Why do open ends have to contain antinodes at their ends? Why can't the wave finish just after or before the pipe ends?

I remember looking at this and rationalizing it as there is a constant wave/sound/something being pushed into the left end of the pipe. Not sure if that makes sense either though.

Sort of off topic...but i would rather study electrochemistry, electromagnetism, thermodynamics, you name it, a month straight with no breaks than resonance and pipes and all that crap...it is sooooo boring and sooo counterintuitive for me....
on the other hand...good luck with it...

We have this constant sound of water running in the kitchen pipes but nothing is on. We flushed all the lines of air and when we did that the sound went away, but the minute we ran the kitchen sink the noise came back. The water pressure seemed better at first then went down. We are on a well and septic system. If it is the pressure release valve or pressure regulator valve where would that be located?

does this have some sort of secret relevance to my question

because i have no idea

honestly TBR's waves chapters are complete GARBAGE use something else i personally used NOVA

I agree. But I was doubting myself thinking that it might be me who's not getting their message lol
I have problem with this concept as well.
