Which infrared category is emitted by low temperature bodies?

Explanation:
Temperature controls which part of the spectrum a body emits. All bodies above absolute zero radiate energy, but the peak of that emission shifts with temperature. At low temperatures, the peak falls in the infrared region, well beyond what the eyes can see, so the radiation is nonluminous infrared radiation. Only hotter bodies emit enough energy in the visible range to be seen as glowing, along with infrared. Therefore, the correct description for low-temperature emission is nonluminous infrared radiation.
