🎶 Resonance Tube: Tuning Fork, Water Column, End Correction and the Speed of Sound

Slide an open glass tube in a jar of water under a tuning fork and find the lengths where the air column rings loudest. See the standing wave of air parcels, measure the speed of sound from two resonances, discover the end correction, and test how temperature, fork pitch and tube radius move the peaks. A time-domain wave solver cross-checks the formulas. Blender-modelled lab bench.
