Uhm. One year undergraduate projects... Lemme see, that would be around the order of EM stuff, right? Well, just off the top of my head what would be a neat thing to find out would be to see if work done on a magnetic field (induced by current) has any affect on the current itself. The...

If you get the chance to run your project in front of some sizable groups (at least seven people), one idea that I saw was to cut PVC pipes to appropriate lengths and color code them. Then by smacking the end of the pipe, you get a distinct frequency from the pipe according to length. To make...

I definitely can't tell you for sure, but maybe my thoughts could help point out a direction you may not have thought of? The optical density of the substance is very likely proportional to k (kappa) which modifies epsilon not (permitivity through free space). An optically dense material...

Oh yeah, and finally... Think positive. Studies show that if you expect to do well, you do much better than if you expect to fail. You rise to your own expectations, in a way.

Peng: okay, I'd just like to comment that it is not the teacher's responsibility to motivate a class. It is his responsibility to facilitate learning, which he may have failed to do, but not provide your drive. If you are in an AP class and are not self-motivated, you are going to fail the test...

I am not sure about this classical model and its relevance to your situation, but in any event, yes I can once again affirm that these people are correct in that EM waves to not require a medium to propagate through. Just a little background on the fascinating theory of light... It used to...

Hey, I just recently had a school physics bowl competition. One of the categories was demonstration (basically a science fair project). A great idea is the michelson/focault speed of light experiment. We worked on this for a while, but it wasn't hard to acquire the materials and was very well...
