Hi Dickfore,
I think I can follow those equations. Is it possible, though, that the quantisation result comes through because the initial assumption/representation of a particle in a box with periodic boundary conditions is only valid for certain solutions, as laid out by the maths? If we had...
Hi,
Thank you all for your kind answers. For my background, I've done most of the first year science subjects (physics, chemistry, biology) but I went on to do computer science with a minor in maths for the rest of my bachelor's degree. I'm also at the end of my PhD, in microanalysis and...
AM, thinking about it a little more, is it possible that induction works on groups of atoms rather than atoms themselves, in the same way that diffraction needs planes of atoms to work?
Quinzio, that's an interesting story. How did he electrify the area around him? Is it related to the...
Me too, Brainguy. I will have to read up on quantum mechanics to understand the answers, I'm afraid. I feel like I'm missing too much information. And it probably shows through my questions. However I do feel like I'm coming closer to understanding the "rules", even though I don't know why the...
I'm asking a form of the 2nd q - i.e. how come em waves come in discrete packets? This may sound like a silly question... but is it possible that space-time itself is divided into discrete pockets? and the em waves must therefore divide themselves up into these pockets, making them into discrete...
Then how does induction work? I would have thought that the explanation would be at a quantum level too, in terms of photons interacting with electrons?
Regards,
Anna.
Thanks for all of your replies.
Dickfore, I don't understand why the eigenvalues would be integer values... in particular I don't understand your statement: "This means that the eigenvalues of the number operator can be changed in unit amounts. Since the vacuum corresponds to zero photons...
Hi again,
If the current induced from electromagnetic waves is in the order of microamperes, how did Tesla light up few hundred watts of light bulbs kilometres away?
Thanks,
Anna.
Hi,
Thanks for your reply - however my maths is pretty rusty. Could you please explain in layman's terms, or define what the symbols mean?
Regards,
Anna.
Thanks AM.
Going back to the question about electromagnetic induction, is it limited to radio waves or can other frequencies like IR, visible light, x-rays and gamma rays induce a current?
Regards,
Anna.
Thanks Gordianus.
If I need the charged particles to go in a straight line, what other options do I have to be able to induce an emf?
And is there an equation predicting how much voltage/current will be induced?
Regards,
Anna.
Hi AM,
Thanks for the info on induction in an antenna.
With the moving stream of particles, what if the charge density was changing/oscillating over time? Would that induce a voltage/current?
Thanks,
Anna.
