How photons move along with EM wave? Found this on why light goes through things like glass: youtube.com/watch?feature=endscreen&NR=1&v=Omr0JNyDBI0 |

Best way to move teaspoon to dissolve sugar in a cup of tea The question was about speed of dissolving, not about energy.. Of course you'll spend more energy because you'll be moving spoon against inertia. If you want to save energy, then just don't use spoon, sugar will dissolve on your own. |

Why does wavelength change as light enters a different medium? @Manishearth, you state: This means that the light wave is altered in some manner, but it's not clear why it's altered, what makes it altering. |

How photons move along with EM wave? @Nic, since Brazz answered pretty the same, I commented his post, could you take a look? |

How photons move along with EM wave? How do they pass over other small particles then if they don't oscillate themselves? Like light wave can jump over some obstacle which looks impossible if photon just goes straight.. |

Electromagnetic wave reflection vs. light reflection Probably to understand this I need to understand what refraction index is from the perspective of EM wave. Everywhere it's just described 'light goes through medium blah-blah', but it's not described why/how this medium changes light as EM wave on the level of particles/fields. It looks to be described here: farside.ph.utexas.edu/teaching/315/Waves/node39.html But need to re-read that several times to understand at least something :) |

Angular frequency. Wrong interpretation at Wikipedia? Yap, that's the problem with such articles - if you're a beginner and you're not strong in these terms, then uncertainties make things even worse. Like it is in my case. |
