The molecule reflects long-wave radiation like a mirror, sending it back towards the ground.
The molecule absorbs long-wave radiation, which increases the vibrational energy of its bonds.
The molecule absorbs short-wave radiation, causing electrons to move to higher energy levels.
The molecule undergoes an exothermic chemical reaction when it collides with a photon.
