〰️ Wave Equation on a String: Impedance Junction, Reflection, Transmission and Energy Flux

Two ropes of different mass per length are joined and stretched by a hanging weight. A pulse or sine burst solves the 1D wave equation live; reflection and transmission coefficients, wave speeds and energy partition are checked against the impedance formulas.
