Adding Color



The day started off with my imaging class. We focused mostly on the angle of refraction and Snell's law. Dr. Pelz showed us an example with a big lens, incandescent light bulb and a piece of paper. We could see a clear image of the "c" when he added a piece of paper with a big hole in the middle on the lens that got rid of the blurry part around it. During our break Joe Pow took us to see Guppy and teach us how to scan our work and then email it to ourselves. Of course I turned out to be the only one with hard copy of the lab and tryed it first. Unfortunately, the copier did not like my email address and spit out a piece of paper that said "FAIL". My papers did not scan. I ended up coming back after class and sending it to Dr. Pelz's email instead. I finally succeeded. After lunch, we worked on figuring a way to stretch our our films. First, Katie and I tried clamping the film and blow drying it. That didn't work. The film didn't seem like it was stretching. When we saw no progress being made, Dr. Swartzlander suggested that we should add a drop of water so it becomes a little damp and then blow dry it. It stretched a little after what seemed like a long period of time. We added a drop of black dye to test the polarization. Since we didn't see any positive results, we went back and used another film and this time added just water and stretched it. We did not blow dry it. It stretched out pretty nice. Added the black dye again. It was too dark to see any polarization. Hopefully tomorrow we will try again with another film and another way. Also maybe use another dye? Well see.
