Which of the following is an example of a use for radar technology?

Radar technology is primarily used for detecting objects and determining their speed and distance. It operates by sending out radio waves and analyzing the echoes that bounce back from objects in the environment. One of the most notable applications of radar technology is in aviation, where it is employed to detect aircraft. This capability allows air traffic control to monitor the location and altitude of planes, ensuring safety and efficient traffic management in the skies.

In contrast, the other options are not suitable examples of radar applications. Listening to music pertains to sound technology, measuring temperature involves thermometers or other temperature sensors, and viewing underwater objects would typically utilize sonar technology, which is different from radar. Therefore, detecting aircraft stands out as a prime use of radar, highlighting its significance in fields such as aviation and military defense.
