They emit infrared light waves. Which is a non-visible light.
Commonly used to provide light for infrared security cameras when there in little to no light visible light Also used in bathroom heat lamps to transmit the heat waves to your skin I believe (not sure) infrared is lower frequency than visible light and ultraviolet is higher frequency than visible light
Much like red light, but lower in frequency. Air is not quite as transparent to IR as to visible light, on the other hand warm blooded, living things glow in IR.
radiation, ultraviolet, infared
The thermosphere contains the ionosphere. The ionosphere is the layer that is ionized by the solor radiation.
Ultraviolet rays or infared rays
The atmosphere can filter out some nonvisible lights like UV and infared rays.
