b) The incoming radiation is infrared. The infrared photons randomly change direction in air.
c) The incoming radiation is sunlight. The visible photons randomly change direction in the air.
d) The incoming radiation is sunlight. The sunlight photons reach the surface of the Earth.
e) The incoming radiation is infrared. The infrared photons reach the surface of the Earth.
f) Both infrared and sunlight photons are observed arriving. The photons reach the surface of the Earth.
