What's the physical significance of using fourier transform for diffraction? I wrote an answer about that here a while ago... |

Rubber band stretched produces heat and when released absorbs heat.. Why? @Nathaniel My final term freshman year project in university was to build one of those. It's been a long time so I don't remember the details, and I think I lost the project report :-P We insulated the water in a styrofoam container to keep the environment from warming it up too much, and it got quite cold to the touch. We weren't able to get it anywhere near freezing though. |

Optical trapping problem You've got the wrong idea about optical trapping. Or perhaps you're referring to something I've never heard of? Can you elaborate? |

Why doesn't my pinhole camera work? +1 for doing your own experiment though! |

Photon energy - momentum in matter actually, three: 1) $p=\hbar k$ is only valid for a photon in a plane wave mode, which people usually gloss over; 2) saying that phase matching is due to conservation of momentum is not accurate, despite it being popular to say in nonlinear optics; 3) of course you are right that the photon is traveling mostly in vacuum and so has $p=h\nu/c$; but that expression is useless at the scale of macroscopic dielectric media. |

Photon energy - momentum in matter I've thought and discussed about it some more and come to two insights: |
