ELI5: Why do remote controls use infrared light instead of other wavelengths?
gpt
Very low wavelength bands are already occupied by radios and microwaves and have a lot of noise.

Visible light is visible of course.

Ultraviolet is too energy intensive to generate, and you definitely don't want to be shooting x-rays around the living room.

So the near-IR it is.
