Acoustic String Dynamics (Violin Bow / Pluck)
A4 (440 Hz)
Fourier Harmonic Weights (n=1 to 5)
Superposition weights
Gedankenexperiment: Phase Velocity & Invariance
Relativity of Wave Nodes
Acoustic Standing Waves & Invariant Nodes
Einstein was known to play Mozart and Bach on his violin ("Lina") while working through physics deadlocks. In a 1-D acoustic resonator, standing wave nodes ($L = n\lambda/2$) preserve zero kinetic displacement regardless of observer frames.
