Our final results were d1=.150+/-.0004 nm and d2=.088+/-.0006 nm and my notebook can be found F08:People/Joseph/Notebook/071128 here.
This was an awful lab. We didn't know what we were doing or why we were doing it. I kept getting shocked. A better circuit diagram would be great. I think it should be scrapped or updated. The intention is great, but its implementation is terrible.
