Light

So I was sick this whole week which sucked because I stayed home (besides the baseball game which I had very important business attending!) Well anywayyyyy, I only remember that I learned about light polarization. We were given filters and looked through them at certain lights such as reflection off of windows. When you turn the filter 90 degrees, it would sometimes turn black and is no longer transparent! Those light particles are polarized! (Because light is an electromagnetic wave! :) Yay for physics!
