A Quincke tube is a way to produce total destructive interference with sound by splitting one sound equally into two paths, and then recombining them. Suppose the speaker (at point T'in the diagram) produces a sound of frequency 1,637 Hz. If the length of the shorter tube is 0.772 m, what is the minimum length of the longer tube, in m, that will give total destructive interference?

A
Right: A Quincke tube. A
speaker produces sound at T,
it splits into two parts- one
part travels upward (through
A) and the other travels
downward (through B). The
two parts recombine, and
come out at O where you are
listening.
B
