Resonance Tube
This interactive simulator explores Resonance Tube in Waves & Sound. Open vs closed pipe harmonics. Hear fₙ and see standing pressure wave. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Waves & Sound.

How it works
Standing sound waves in a tube: allowed frequencies depend on boundary conditions. Open–open: fₙ = n·v/(2L). Open–closed (one closed end): odd quarter-wave modes, fₙ = (2n−1)·v/(4L). The animation shows a pressure-like pattern (schematic). Use Play to hear the selected harmonic.
