Electromagnetic theory as explanation for all types of visible light and all EM radiation: Light polarisation rotates in a magnetic field (Faraday rotation), i.e. light is connected and reacts to magnetism. ... Since we can see atoms emitting visible light (some of them), this has to be electromagnetic (see e.g. LEDs).
