Standing waves can be established within a cylindrical volume. However, it is not known if the volume is closed at both ends, open at both ends, or is open at one end and closed at the other end. Three successive resonance frequencies within the volume are f1, f2, and f3. How can a student use the information to determine if each end of the volume is open or closed
