Measuring the speed of light with chocolate and a microwave

See, you don't need to go to MIT. ;) Just teasing.

Damn, you beat me. http://physics.about.com/library/weekly/aa012703b.htm

It works though. I did the thing with thermal fax paper in the microwave it and worked the same. Found all the antinodes in the microwave and now i know where to put the food so it gets a better cook.

Placer14... hehehe. I've seen similar experiments before with things other than the microwave. In my modern physics lab way back in undergrad school, we did something similar, except we measured the frequency with an oscilliscope (rather than saying, oh, its what the back of the microwave says for sure). And we got less than 1% error. Go figure.

For the original poster: if you're looking into the "faster than light" issue, be VERY careful. I thought "cool" when we read about theories in physics class (I'm an engineer by education, though), but its an "odd" topic in physics. It can be an interesting one, but if you go off half-cocked and really don't delve into the details, you're going to get branded as one of those kids who thinks Star Trek is real. And it sounds as if you're sincere... so do your homework.... learn a bit. I think you MIGHT be a bit ambitious (from what you stated in your previous post)--but the most important thing is that you might learn some modern physics early and in your own way.

Basically, what matter can go from one place to another in zero time. Doing this more for myself and to learn about this, seeing as unless you prove your hypothesis, you won't win anything in the WestingHouse Scholarship.

Ok here's my take on all this. Since light can be viewed as waves with no mass, it isn't limited by its speed inside a vacuum. You can excite cesium to a special gaseous state that resonates with the light frequencies and push laser pulses through the gas. Light there interacts with matter at quantum levels in a manner analogous to spectrum scattering through a prism, and it reforms at the opposite end of the test chamber at virtually the instant the tip of the pulse touches the chamber entry. You (well maybe not you) can actually observe the light leave before it enters. I suggest reading up on coherent radio waves in the terahertz range. This way you can prove it actually exists in nature as well as in a lab.

BTW what dimension are you trying to prove this in?

Hmm.. does it matter? I can do 4th dimension if need be, seeing as we're getting into that in Calculus.

Right now I'm reading Schroinger's Kittens and E=MC^2. I clearly need to do more reading on this... :p

Anyways, time to get ready for bed! Got school in the morning, and tomorrow I have two hours of math, yay!
