Question

what is one use of infrared? tv remote controls am radio aircraft communication

Explanation:

Infrared is used in TV remote controls. Infrared technology allows for wireless communication between the remote and the TV. The remote emits infrared signals that the TV's sensor detects, enabling functions like changing channels or adjusting volume. AM radio uses radio waves (not infrared). Aircraft communication typically uses other radio - frequency bands. Night vision goggles (which are related to infrared but not the same as TV remote use) and other infrared applications like thermal imaging are different from the basic function of TV remote controls shown in the context of this question.
