WebHow a Radio Works Radio waves are beams of light sent out by the station's transmitter antenna that you can detect and convert into sound. Because the wavelength of radio light is so much longer than that of visible light, it behaves quite differently; but it is still light: energy that propagates by oscillating the electromagnetic field. Web2 de out. de 2016 · This good sense means we can make the receive antenna to maximize the signal but, making it smaller isn't necessarily a show-stopper; you will likely get a smaller signal but that doesn't mean it can't work.
