  Something that I thought was confusing about light is how the eye sees the image.  I know that your eye takes in rays in the pupil and turns them.  But how do the rays turn?  And how come the rays only go into the pupil and not your whole eye, its not like your eye can attract light?  I figured out that your eye is like the cardboard experiment and the rays can only go through the hole, and they flip just like the candle flame.  I still do not understand the reason why the rays only go into your pupil and i definitely do not get how the rays can travel all the way up to your brain without being stopped.

I understand how light travels very fast in air and slower in water.  Since water is denser than air it refracts and the water waves are closer together.  The running thing made sense and helped me understand it more.  LIke when Jackie, Laura, and Perry had to weave through everyone they couldn't run as fast as they could normally.
