Little packets of light
It's a physics thing...
I've been reading this book at lunch and in one of the diagrams it looks like when a photon hits an electron the electron changes direction. They don't say if the photon has mass or not and it's been bugging me...
Sorry Cheyenne..... Here... have some coffee...

I think magnetic fields may be the answer, but I was a gawdawful physics student...

Whoa, mind reading. I posted before I saw the question...

actually on further reflection, they have a charge electrically, but I think on that scale both are tightly linked.
I think I need to go do some brush-up reading.
Questions like this call for Texan or Cymbadia to answer, not the board retard...

The electron has a charge and hence a magnetic field...
PLEEZE TEXAN, rescue me, I'm drowning here!

um.... half a magnetic field..., but I don't think that has an effect on the photon....
The electron absorbed the photon and changed direction....
Hmm.... now that i think about it, the electron sped up when it absorbed the photon, then slowed back down after emitting it.

Photons as you pointed out are little "packets" of energy but are massless. Photons are that portion of electromagnetic energy that stimulate the human eye where say an X-ray, radio "wave" or gamma ray does not. If a photon had any mass at all, it would have nearly infinite mass at the speed of light by the laws of Einstein's rules. If you turned a flashlight on it would fly backwards from your hand at tremendous acceleration or you would wipe out of existance everything touched by the "beam".
The "movement" experiment may better describe how "laser" light works. Lasers are capable of piercing small holes through solid material without imparting force to that object. It must be explained by the rapid increase in energy levels of the electrons in the object. Try searching and understanding that.

hehe... don't worry, I won't pull up some old threads.
But I do think I need that back rub. Tension in rl combined with immaturity on the board this morning is a bad combination for me, it seems.
And you have no reason to blush, you give great back rubs! I remember well.

That's what I thought. So what you're saying is, it's an energy thing and not a mass thing.... When the electron absorbs the photon it's kinetic energy increases so it moves faster and when it emits the photon it's KE goes back down to the original..... ok.... that makes sence.... thanks...

I thought that was just heat transfer...
