Radio in daily life is used as a means of transmitting information. The sound we hear from the radio is a change in the shape of the electromagnetic energy of radio waves captured by the radio plane, then converted through the loudspeaker into sound energy so we can hear it.
The sounds we hear from the radio can be about entertainment, such as music, humor and news and other information. So the mention of the term RADIO in general is still ambiguous. The first sense is: tool / plane to convert radio waves into sound waves. The other meanings are the waves that are part of the electromagnetic waves.
