Students will have no difficulty hearing resonant frequencies from this tube. Two nested cardboard tubes allow the length of the air column to be easily varied. And the inner tube contains a removable end-cap to change from a “closed” to an “open” tube. The length of the resonating column can be read directly off the metric scale for both open and closed operation.
