Radio photon ν ~ 10⁸ Hz E ~ 10⁻⁷ eV CW CCW c Visible photon ν ~ 10¹⁴ Hz E ~ 2 eV CW CCW c Gamma photon ν ~ 10²⁰ Hz E ~ 10⁶ eV CW CCW c ≈ λ Same envelope. Same speed. Different internal winding. E = hν encodes the intensity of counter-rotation inside the soliton. The electromagnetic spectrum as modon winding density Radio Micro IR Visible UV X-ray Gamma Increasing internal vorticity Why all photons travel at c The translation speed is set by the envelope-background interaction (C1), not the internal energy.
