How a crystal radio works
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. Web1 de jan. de 2024 · The sound from an unpowered crystal radio is very faint. It’s best listened to at night in a very quiet room! To make it easier to hear, we connected the output from our crystal radio circuit to an audio amplifier. And here’s what our AM crystal radio looked like. Supplies to Make a Radio.
