4/16 Han

Today was another semi-wonderful day in Coats-Haan's favorite 3rd period class. The start of class was pretty good, continuing with our "Lights and Media" notes that we had begun on Friday. We learned new concepts such as Fermat's Principle, the law of reflection, what causes refraction, and Snell's Law. We also took time to debated the pronunciation of Fermat's name for a short period of time. These notes consumed most of the class time. We also did the two examples that went along with the notes on the back of the "Brain Busters" worksheet. After we completed our notes, we moved on to another lab that we had to do in class and complete for homework (one of the many grueling assignments that was given to us). The lab had the same steps as the refraction experiment we did on Friday, except this time we were required to calculate the refraction index of our two trials. Our homework for the night was to complete this lab, as well as page 199 in our lab manuals, and page 846 #'s: 1-11, 13-15, and 18. When light enters a medium, it moves toward the medium if traveling slower. This happens because the lights refraction index is greater, causing it to bend toward the medium.
