Final answer:
Radio waves are a type of electromagnetic wave that travel at the speed of light and carry information. The relationship between radio waves and movement is demonstrated by the Doppler effect, which causes a shift in frequency due to the motion of either the source of waves or the receiver.
Explanation:
Radio waves are a type of electromagnetic wave that are used in various technologies like radio signals, wifi signals, and cell signals.
