Just saw a video about how the shadow on moon is pitch black.
That took me to the question of scattering. I have myself asked a question similar to this already.
When light from a bulb(consisting of whole blackbody spectrum) hits/interacts with the air molecules, it gets absorbed. Then, the molecules and electrons of molecules themselves vibrate with the frequency of the incident light and radiate light of their own (which is again blackbody spectrum mainly).
Now, in a room the shadow is formed dur to the blocked light from light source. But the air behind the blocking object emits light which illuminates the shadow region.
In a sense the air molecules are small light bulbs which are all around the room.
Also, scattering is mostly understood as light 'bouncing' off the atoms here and there, but I don't really like this way of thinking about it.
How correct and incorrect is my understanding regarding this. (Please point out any missing/incomplete pieces of important knowledge I seem to lack.)
