Darn it, i absolutely love science. But Amy Mainzer makes my focus drop like a freestyle counterweight.
She is just too hot for science.

@vinylandtubes LOL, that's a silly question. Imagine I shoot you with a gun in the stomach. The bullet will slow down going through your body and get out of you going in the same direction as it entered you - through your back obviously. You don't have to "know" anything for it to happen.

@imnumber0ne01 Forgetting stuff is no fun...
-
@raydredX Just forget it lol
-
@vinylandtubes Good question - they don't know which way to re radiate - they radiate in every possible direction. But the waves from each atom superimpose and some cancel out and some stay....What you observe is the light than stays. Infact you can solve these equations based on this and the results will be exactly that of reflection, refraction and diffusion :)
-
@imnumber0ne01 But we can see through any fluid colloid or not, even if they call it opaque light can still pass through. And we can see through breaks in the clouds because there isn't as much cloud density there. And we can see the rippling, bending and blah blah in the water because the velocity changes, because the change in the velocity is the reason that there is refraction or "bending".
I'm sorry if my answer sucks but I don't understand completely what you mean.

@raydredX Colloids are fluids that have floating particles in them that allow us to see where the light is traveling through, such as when there is a break in the clouds. It isn't caused by a change in speed. Amirite?
-
@imnumber0ne01 How does that change anything? And to see the light in the water I just need to dive in, why would I need colloids? Would you care to explain?
-
Lol the first woman is an idiot, colloids allow us to see light in water

How does the glass atom know exactly which direction to re-radiate the light particle?

they are arranged in such a way ....
