Hi all, I stumbled upon this site while searching for explanations to a Homework problem. I'm a decent student, but I'm certainly not the best. I'm currently enrolled in two physics courses at my college (Electricity & Magnetism and Optics). I'm doing pretty well in E&M, but Optics is kicking my butt. The professor spends must of her time chatting about random stuff, which is not helpful. I'll do my best not to bother you guys too much with simple problems unless I'm really stumped. This should be an interesting group.
