Test Thursday.

For the test, you should understand Mirrors, reflection, refraction, and Snell's law.
To complete the review work from last night and today, you should understand that the index of refraction can be determined by dividing the speed of light (c) by the speed of light in the material. Because most of you understand algebra, then you know you can also determine the speed of light in a material as long as you have the index of refraction number.
We can also detemine the angle of the light by following snells law. which is n1(SineAngle1)=n2(sineAngle2). If you have three parts, you can figure out the rest.

If you want to start looking at topics that will be on the Final This is a good document to look at. More or less, all of the vocabulary we covered this semester is on there.
