Question

which best describes the way a sound wave is sent through the radio? sound wave → radio wave radio wave → sound wave radio wave → sound wave → electrical signal → sound wave sound wave → electrical signal → radio wave → sound wave

Explanation:

First, the sound wave is converted into an electrical signal. Then, this electrical signal is modulated onto a radio wave for transmission. At the receiving end, the radio wave is demodulated to get back the electrical signal, which is then converted back into a sound wave.

Answer:

sound wave → electrical signal → radio wave → sound wave
