Hello. I'm trying to understand electromagnetic radiation. Any help would be appreciated. From my understanding a photon is a basic "unit" of electromagnetic radiation with an energy corresponding to hv. Additionally radios transmit electromagnetic waves by sending an AC through an antenna. The amount of EM waves transmitted is a function of the power supplied by the radio. As a thought experiment, if we continuously reduce the power supplied to the antenna, will we reach a point where there would be only one photon emitted (corresponding to when E=hv; P=hv/t)? Then will no radio waves be emitted below that power? What will happen if the antenna receives 1.5 times the power (when E=1.5hv; P=1.5hv/t); will there be only 1 photon emitted and the remaining energy lost as heat? Thanks.
