Fuck Physics...

[Sabb]

So I did a lab for physics (optics), have to fill a lab report on it, but it doesn't fucking make sense ._.. Light is shone through a semi circle of lucite. The light refracts off the levelled edge, but not the curved one. I can't figure out why... In the experiment the light rays pass through the center of the circle, so at its radius. I'm guessing it has something to do with that but I can't figure out what. If you understand optics, or need more information, please post. Really need help here.

I haven't dealt with light physics but I've had extensive studies in physics o-o

Probably more helpful with mechanics but might be able to help.

Are there any diagrams to help visualize the problem or maybe the lab report itself to understand what's going on a bit clearer.

Nop.
All I can give is the data as that's all I've got. And that's only the angel of incidences and angles of refraction.
This is basically what I'm talking about though:

It also doesn't matter which medium the light enters and exits, no matter what the light doesn't refract at the curved edge.

EDIT:
It's actually the opposite of that image, sorry...
Can't find an image showing the light not refracted from the curved edge, but I think you get the point.
I'm also starting to think it could be due to the shape of the lucite maybe? So that at the angle it's entering/exiting that edge, it could simply be refracted, but by a very small amount?
Or possibly that it's technically entering on a 90 degree angle through the normal... but I'm not entirely sure. The actual lucite we used was a complete semi circle btw, not like that in the image where it's not really half a circle.

I remember this lesson a couple years back.
Hatted it so much.
I played pokemon through most of it secretly so I can help you here man.

LOL okay.
I also have a test on this tomorrow.
And the lab for this was due two days ago.

Got it figured out. It is to do with the position of the angel of incidence and the perfect circular shape. Always exits and enters on a 90 degree angle, moving along the normal, though it doesn't really look like it. Thanks anyways.
