For instance, the sky is blue because the blue and purple part of the light spectrum has a very high frequency so the blue and purple light photons are colliding with air particles more often then the red part of the light, so blue light gets separated from the rest of the light ray and scattered in all directions so it makes the air look like it is emitting blue light. But I was wondering what happens to the air particles when that are hit by blue frequency photons, I thought to myself that they would go into a spin because two forces are acting on them, the photon hitting the atom and the other atom it is connected to is holding it. But the answer is I don't know. I don't know if the air molecules spin when they are hit by light photons or just bounce of the nearby molecules like snooker balls or they they just vibrate like a bell. I just don't know.
This is what I am looking at.... My own ignorance.
Then I am left with even more questions, if the air molecules do spin when they are hit by light photons then would it effect their magnetic properties. Nitrogen is mildly repelled by magnets and oxygen is slightly attracted to them. But magnetic fields are directional, if the molecules are spinning then would that not make them less magnetic as a group? I don't know, I know so little and feel so puzzled.
