How does a radio work?
Radio is the receiving end of the signals originating at distant radio stations.
During a radio programme in the studio, the voices and music are turned into electronic signals. They are amplified and then sent out as radio waves from tall transmitting aerials. The radio at our houses picks up these signals and change it back into the sounds that we can hear. The tuner inside the receiver helps to pick up one signal or station. The amplifier make the sound signals stronger and passes it to the loudspeaker that change these signals to sound which can be heard in the form of voices or music by us.
