Radio waves, as electromagnetic waves, differ from sound waves which require a medium to propagate. Microphones convert sound to electrical signals, then into radio waves for broadcasting.
RADIO WAVES are a type of electromagnetic wave that does not require a medium to propagate, unlike sound waves, which rely on particles in a medium like air to transmit. In the context of radio transmission, a microphone picks up sound, converts it into an electrical signal, which then gets transformed into radio waves by a transmitter before being broadcast through the air to be picked up by a radio antenna.
