WebIn its most common form, radio is used for the transmission of sounds (voice and music) and pictures (television). The sounds and images are converted into electrical signals by a microphone (sounds) or video camera (images), amplified, and used to modulate a carrier wave that has been generated by an oscillator circuit in a transmitter. Web1) The transmitters electrons oscillate to create radio waves. 2) When the transmitted radio waves reach a receiver they're absorbed. 3) Energy carried by the waves is transferred to the electrons in the material of the receiver. 4) Causing the electrons to oscillate if part of a complete electrical circuit will generate a alternating current.
