Heat is the energy of random molecular motion. Does this mean then that atoms are constantly producing energy since the electrons are always moving? Or is it that there is potential energy stored in those electrons' motion? Would this be the energy of an atom bom?
If entropy always...
thx
Thanks Adrian, and previous posters.
I understand the experiment fully now. I did my presentation using the experiment and got a 96% - at my grade eleven level, the teacher was impressed. And one more thing. I noticed that if you shine the laser at the back of the cd on that inner...
Correction
Ok, I've gotten the dots in a perfectly straight line now. I believe it was curved before because the laser was not exactly perpendicular to the cd.

I've reread the section in QED and i still can't see how the dots in a line disprove the law of reflection...
Interpretation?
Okay! My partner got a laser and we tried the experiment yesterday. When we point the laser beam at a certain angle to the cd, we see 3-4 dots that are not equally spaced form a gentle curve, almost a straight line, on the wall or blackboard in front of us. Is this what we are...
Hello,
I have purchased, read, and understood the concepts in Feynman's book QED: The Strange Theory of Light and Matter. I would like to reproduce the diffraction grating experiment (on pg. 50 for those who have it) for a physics presentation at school in order to prove that light doesn't...
