Which term describes the process of moving radio waves through space?

• A. Datalink
• B. Transceiver
• C. Wave Propagation
• D. Antenna Gain

Answer: (C)

Wave propagation describes how radio waves travel through space. It covers how the signal moves from the transmitter to the receiver and how factors like distance, obstacles, reflections, diffraction, and atmospheric conditions affect it—key ideas for understanding drone communication ranges and reliability. The other terms refer to different concepts: a datalink is about the data transfer method between devices, a transceiver is the hardware that both transmits and receives, and antenna gain describes how an antenna concentrates energy in a direction rather than the act of moving waves through space.
