    How Does Atomic Motion Relate to Heat and Entropy?

    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...

    Exploring QED: A DIY Diffraction Grating Experiment for a Physics Presentation

    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...

    Exploring QED: A DIY Diffraction Grating Experiment for a Physics Presentation

    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. (laser------- |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...

    Exploring QED: A DIY Diffraction Grating Experiment for a Physics Presentation

    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...

    Exploring QED: A DIY Diffraction Grating Experiment for a Physics Presentation

    thanks Thanks for the great ideas guys. I don't have a laser at the moment but i'll try the experiment out when i get one. Merry x-mas!

    Exploring QED: A DIY Diffraction Grating Experiment for a Physics Presentation

    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...
