Acoustic Apparatus

Acoustic Apparatus

Usage conditions apply
This apparatus, which consists of two glass pipes of different diameters mounted on a vertical stand, shows that the sound produced by a column of air is a function of both diameter and length. It came from the Smithsonian Institution Instrument Room, was probably made by Koenig in Paris, and was probably purchased by Joseph Henry, the physicist who served as founding Secretary of the Smithsonian.
