Included Quiz Questions

Why must the pressure (difference from atmospheric pressure) in a pipe be zero at the open end?

Air at the open ends can always move freely and equilibrate with the atmospheric pressure outside the pipe
The open end cannot resonate like a closed end
The air cannot bounce off the walls of a closed end to create pressure
The open air is unable to be moved, and cannot create pressure
The open end of a pipe cannot store energy for pressure to accumulate

What is the relationship between allowed frequencies in a pipe with two closed ends and a pipe with two open ends if the pipes have the same length?

The same frequencies are allowed
The closed pipe can have frequencies twice as high
The open pipe can have frequencies twice as high
The closed pipe can have frequencies that are v/(4L) higher than the open pipe
The open pipe can have frequencies that are v/(4L) higher than the closed pipe

What boundary conditions must be satisfied for a pressure standing wave in a pipe with closed ends ? Choose the best answer.

The pressure at either end can be maximized or minimized but at the same time the pressure at the other end must be minimized or maximized, respectively.
The pressure at both ends can be maximized or minimized in an arbitrary way.
The pressure at both ends must be fixed at zero (or atmospheric pressure).
The pressure at both ends can be maximized at the same time or minimized at the same time.
The pressure at either end can be maximized or minimized but at the same time the pressure at the other end must fixed to atmospheric pressure.
