Low-temperature bodies emit which type of infrared radiation?

Explanation:
The main idea is that thermal emission depends on temperature: cooler objects radiate primarily in the infrared and don’t glow visibly. A low-temperature body’s spectrum peaks in the infrared and there isn’t enough energy in the visible range to produce light you can see, so the radiation is nonluminous infrared radiation. Only when the object gets hot enough to emit visible light does the infrared radiation become luminous infrared radiation.
