Well, I have some physics background. I just graduated the ib course physics higher level.
So what's your point? That I'm wrong in asking? That I should rather borrow a book instead of bothering the forum? That I'm naive, trying to learn it without a teacher or a book? The least you could do...
No reason. I'm just interested in how things work (isn't that the whole reason you study physics in the first place?). Take glass for an example. The question I posed in msg.1 will do, I won't be demanding much more than that...
Also, as opposed to what you state in your FAQ about quantum...
Yes, http://en.wikipedia.org/wiki/Electronic_band

- so kind of a description of the first energy of ionisation, or the "work function" as in the photoelectric effect?
So you're saying that the photon energy has to be large enough to...
"The lattice ions react to the oscillating electromagnetic field of the photon and e.g. gain energy from it, then retransmit"
So how would the lattice of ions together with the electrons react? By modes of vibrations? As heat - that is? But that goes, as the FAQ said, not to reemission then...
Well, now I have, but it still doesn't answer my question; just makes me more confused. It stated that the lattice of ions and electrons form some sort of phonon absorption spectrum which is similar to the eigenfrequency of objects - so that photons outside the possible absorption range will NOT...
The question is, how exactly it is that light can travel slower when not in vaccum, and how for example Bose-Einstein condensates can be used to slow light a lot, or even stopping it? http://www.osa-opn.org/abstract.cfm?URI=OPN-16-5-30
I've read...
The only thing with barriers with electrons that I know of is about electron tunnelling.
Signlalling hormones in the body don't just 'pop up', they are part of complex chemical reactions creating them.
bump!
Just a few minutes ago I read a sentence "it only allows through phontons whose electric field is oscillating in the same direction as the molecules" when reading about the polarimeter detecting what type of optical isomer a compound consists of.
Has the elecric field of the photon...
Hello!
Question one: How do u measure the surface tension? (I'm looking for the experimental method now, not the theoretical one by itself)
Question two: When ejecting water droplets at a high velocity at a small angle to a water surface/body, the droplets might not merge with the body of...
Hi!
I'm investigating whether you must use a logarithmic formula to describe a helix, or if it's enough to use two phase shifted sine curves... I've done a little excel document with a very siple implementation of two sine curves. One normal with the amplitude 23.8 and another one with the same...
I found yet another, even more high pitched frequency that I can hear... (of course, there is no way for you to verify that I hear it... Although you might analyze the video)

The first video - a quite high frequency, with a quite low amplitude. It...
Hehe, good to know, didn't know that the De Haas effect didn't work under the 100-200 range. I saw a couple of headphones (is that what you call them?) today in a store with a range from 10-24k Hz.
Do you know any way to test my hearing? It'd be fun to know my hearing limit.
So ultra- is...
Try that:

and click on sound - I really think it has a low frequency - nothing in the vincinity of the TV sound... Sounds more like some kind of a kettle of hot water boiling... And sensing? I mean... we have no membrane on the outside of our...
