📘 Description
Angular Wavenumber (rad/m)
Unit: rad/m (radian retained for meaning)
Definition: Spatial phase rate: how fast a wave's phase changes with distance.
Core relationships:
k = 2π/λ- Phase:
φ(x) = kxfor a simple traveling wave
Interpretation: Large k means rapid phase winding in space (short wavelength).

📜 Historical Background
Historical Notes
Angular wavenumber is the natural wavevector magnitude in physics because it aligns with radians and Fourier analysis, simplifying many differential equations.
