How does a radio station transmit a radio signal to your ear?
A) The station's antenna sends an electric current through a wire that runs from the radio station to your radio, causing the radio to send sound waves to your ear.
B) Electrons moving in the station's antenna send out a sound wave that travels to your radio, where the wave is amplified and sent to your ear as a more intense sound wave.
C) Stationary positive and negative charges residing on the station's antenna exert electrostatic forces that act on your radio, causing the radio to send sound waves to your ear.
D) Electrons moving in the station's antenna send out an electromagnetic wave that travels to your radio, where the wave is amplified and sent to your ear as a more intense electromagnetic wave.
E) Electrons moving in the station's antenna send out an electromagnetic wave that travels to your radio, where the wave is transformed into a sound wave that travels to your ear.
