What technology uses radio waves to detect the distance, speed, and direction of objects like aircraft?

Explanation

Radar, short for radio detection and ranging, works by sending out radio waves that reflect off distant objects and return to a receiver, allowing the system to calculate the object’s distance, speed, and direction. It is widely used in aviation for air traffic control, in weather forecasting to track storms, and in maritime and military navigation. The time delay between sending and receiving the reflected signal is used to determine how far away an object is. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
