Cell phones are widely used by people all over the world as a medium of communication. When a person makes a call from a cell phone, the cell phone emits electromagnetic waves that are intercepted by a nearby cell phone tower. The cell phone tower then connects the call to the phone of the person being called.
Which of the following processes enables a cell phone to receive communications from a cell phone tower?
A.
Electromagnetic waves from the tower produce an electric current in the cell phone's internal circuit when intercepted by the phone's antenna.
B.
Electromagnetic waves from the tower are reflected by the cell phone, producing an electromagnetic field that is detected by the internal circuits of the phone.
C.
Electromagnetic waves diffract around the cell phone's antenna, which allows the waves to be detected by the internal circuits of the phone.
D.
Electromagnetic waves from the tower interfere with the radio waves emitted by the cell phone, producing electric currents in the internal circuits of the phone.
