A longitudinal standing wave can be created in a
long, thin aluminum rod by stroking the rod with very dry fingers.
This is often done as a physics demonstration, creating a
high-pitched, very annoying whine. From a wave perspective, the
standing wave is equivalent to a sound standing wave in an
open-open tube. In particular, both ends of the rod are anti-nodes.

aluminum rod? The speed of...
