Would cell phones work if we had no atmosphere?
Radio waves, like to and from your cell phone, are light waves…more properly electro-magnetic waves, which include light, radio, X, gamma, and a whole host of things. They are all EM waves and they all travel at light speed. As EM waves are formed by photons moving as groups, the photons are themselves the “medium” through which the waves travel. This is like water molecules that form ripples on a pond. To a point, the EM waves used by cell phones would actually work better without an atmosphere. This results, because there would be nothing to interfer with the photons as they travel through space. Thus the energy produced by a cell phone would go unabashed by atmospheric interferences.
