Question

Quizplus · Accepted Answer

Microwave transmissions send signals in the gigahertz range to relays in the line of sight, which can span more than 20 kilometers when earthbound. Microwave waves are shorter than radio waves, but longer than infrared radiation, making them useful for communication purposes. They can also be transmitted to satellites, making them a crucial part of modern communication and technology.
