comment Factors defining interaction between atoms and molecules
I assume that depends on how deep the answer will be :)

comment 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

comment 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.

comment 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.

@Nic, since Brazz answered pretty the same, I commented his post, could you take a look?

comment 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..

comment 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 :)
