Reflections From a Barrier
A wave is reflected from a barrier with a phase reversal. This is the behaviour for transverse waves and the displacement aspect of a longitudinal wave.

Reflections From Two Barriers
A wave is reflected back and forth between two barriers, setting up a standing wave.

Standing Waves With a Node on Both Ends
The first three standing waves for nodes at both ends. The frequencies of the waves are proportional to one over the wavelength.
