Today in Honors Physics we learned about 3D vision and interference. We didn’t have any homework to check over or to turn in, but it would have been wise to start working on the Physics of Bling. Before we got into our notes, we had a contest to see who creped on Amalea the most. Nathan won by a landslide stating that he saw Amalea getting into bed last night, Mr. Ebersole expresses how awkward that was, and decided we needed to move on. Our notes were titled Polarization and 3D Viewing. Within these notes, we learned about polarization, common light sources, polarized filters, a filter's effect on light intensity, depth vision, and different objects that were affected by polarized filters such as 3D glasses, View Masters, and 3D movies. During this presentation, we learned how the 3D glasses at Rave work. The glasses have two polarized filters: one with a vertical component and the other with a horizontal component. Having these two filters allow us to filter the vibrations of light to travel through allowing us a different image for each eye.  If you weren’t in class, you’ll need to email Mrs. Coats-Haan to obtain a copy of these. Once we got through out notes, we had the rest of class to work on the Polarization Practice Sheet within pages 209-212 of our lab manual. If we didn’t finish these questions, we had to finish them for homework and turn them in tomorrow. We also have two other homework assignments which are due on Monday: The Physics of Bling and Diffraction and Interference Reading Questions. We’ll also have our study guide for the light test (Wednesday) given to us tomorrow so we can start working on them tomorrow. Remember, stay classy!

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.

4/16 qod

Does light bend toward the normal or away from the normal when it enters a medium that is travels slower in than the initial medium?  Explain your answer.

For all the groups that had finished the laser golf lab, they turned it in.  During class the one group that had not finished the laser golf lab had to complete it in addition to working on the refraction experiment and reading.  In the lab we drew a line on a side of the glass, and then tried to continue the line on the other side by looking through the glass.  After the lab we took notes and started an example problem.  As Mr. Ebersole was going over the notes, he kept on stumbling on explaining them.  While the card is moved away, I believe the light is refracted within the glass and it produces the mirror image instead of the authentic view of the card.
