which best describes the way a sound wave is sent through the radio?\no sound wave → radio wave\no radio…

Brief Explanations:

In a radio, first the sound wave is converted into an electrical signal by a microphone. Then this electrical signal is modulated onto a radio - wave for transmission. At the receiving end, the radio - wave is received and converted back into an electrical signal, which is then converted into a sound wave by a speaker.

Answer:

sound wave → electrical signal → radio wave → sound wave
