Can you see infrared radiation emitted by a TV remote with your naked eye?

Explanation:
Infrared radiation is outside the range of what the human eye can see. TV remotes emit near-infrared light, around 940 nanometers, which our eyes don’t detect (we see roughly 400–700 nm). So, when you look at a remote, its beam is invisible to naked sight. If you want to observe it, you’d need a detector such as a camera or an infrared viewer that converts IR signals into a visible image. Ordinary glasses won’t reveal infrared light.
