Test Tomorrow

Here is the link to the smart notes on the test. A little birdy told me that you need to study the electromagnetic spectrum and know what the parts of it are used for, the order of their wavelengths, etc. The birdy also let me know that you will need to know about transparent, opaque, and translucent materials. It would also be helpful to know about polarization of light. The last few chirps were something about the wave/particle properties of light, and how fast they go.
