The representation of sound vibration in pipes is usually this:
since sound is made of longitudinal waves, what does the sinusoidal wave represent?

you're wrong. I got to it first ;D
question: why do closed ends of pipes have to contain a node? why do open ends have to contain antinodes?
book says: there is always a displacement node at the closed end (because the air is not free to move) and an antinode at the open end (where the air can freely move.)
if air cannot move shouldn't it be a rarefaction?
NO WAIT a rarefaction indicates air movement. The only one that doesn't indicate air movement is node.
i'm on a roll!
