Answer to Question #172110 in Electric Circuits for amanda

Question

Suppose a transmitter B with antenna is emitting radio waves to receiver C at far away distance. If a receiver D that is receiving a higher frequency radio waves is placed to next to transmitter B, would there be a super imposing of the waves? Would there be interference or disturbance? What would be received by the receiver C?

Answer 1

When the electromagnetic radio waves hit a receiving antenna, or receiver, such as a radio, it generates a current inside of a wire in the receiver. (The reverse process of what happened in the transmitter when the current generated the electromagnetic field in the first place.) The receiver then processes the current back into the transmitted information, which, for a radio, allows you to hear music or other broadcasts. Some materials can block the radio waves that the transmitter generates, which can be tested by seeing whether a receiver can process and respond to information sent by a transmitter.
