radio broadcasts
Radio broadcasts involve transmitting sound signals through radio waves, which are a type of electromagnetic wave. A radio station creates audio content and converts it into electrical signals, then encodes these signals onto radio waves using a method called modulation. These waves travel through the air and are captured by radio receivers, which demodulate the signals to recreate sound. This allows people to listen to music, news, or other programs wirelessly, using simple radio devices. The process relies on frequency allocation to prevent interference, and stations broadcast over specific channels for listeners to tune in easily.
