The ↭ (Left Right Wave Arrow) symbol features a bidirectional arrowhead attached to a serpentine, wavy shaft. In Unicode, it sits within the Arrows block and is primarily used in mathematics, physics, and engineering to represent oscillating relationships, wave functions, or alternating current. Beyond technical documentation, it serves as a quirky visual indicator for a turbulent exchange, wobbling, or back-and-forth motion.
