AM Radio is in the frequency range of 500 kHz to 1 MHz

Explanation for how radio signals are detected "An AM receiver detects amplitude variations in the radio waves at a particular frequency. It then amplifies changes in the signal voltage to drive a loudspeaker or earphones. The earliest crystal radio receivers used a crystal diode detector with no amplification."

I don't think radio waves have a voltage...maybe power differences?
