What's so special about resonant Frequencies ( or length of the pipe) in an pipe:
As I understand it, if any two waves pass by each other in different directions, they will create a sort of standing wave with anti-nodes and nodes ( hence beats).
They always show diagrams of Displacement with an displacement antinode at the end (ex http://hyperphysics.phy-astr.gsu.edu/hbase/waves/opecol.html ) . Why is that? What if the pipe wasn't a perfect length to create an anti-node displacement at the end. Wouldn't there still be nodes and anti-nodes in the pipe ? ( assuming it's long enough) . There would still be a reflected and incident wave interacting and creating nodes and anti nodes. So why does a particular frequency matter
