Light does not share enough similarities to electromagnetism to be considered the same phenomena.

- Microwaves, radar, and radio can be transmitted through the air by flowing electromagnetism(electricity) through special geometries of conductive material(antennas), but there does not exist an antenna that can transmit light through the air.
- Materials that are conductive to electromagnetism are distinct from materials that conduct light. Copper, silver, and other electrically conductive materials do not allow light to flow through, because the light bounces off the conductor. These electrically conductive materials are always shiny, almost as if excluding light from the material was the reason they are conductive. Glass, polycarbonate, and other optically conductive materials almost exclusively do not conduct electrical energy. Almost as if optical properties in a material are dependant upon the material excluding electricity.
- Visible light, ultraviolet, and infrared all have optical properties that are not shared with electromagnetism.
- There does not exist microwave photons, radar photons, or radio photons: you have never heard those terms ever used.
- Light does not exhibit any magnetic properties
- While many materials will transduce electromagnetism into light, and light is emitted by high voltage electromagnetism flowing through the air: both require a specific material that can convert electricity into light. The light only started to exist when the electricity hit the material; the light was not flowing in the material.
