Can infrared radiation be reflected

WebFeb 19, 2024 · “CO 2 molecules absorb infrared light at a few wavelengths, but the most important absorption is light of about 15 microns,” says Kroll. Incoming light from the sun tends to have much shorter wavelengths than this, so CO 2 doesn’t stop this sunlight from warming the Earth in the first place.
