so if I understood this whole discussion correctly, the only thing that would change when the infinite plate is grounded is the magnitude of the image charges? I was reviewing my E&M and got stuck on this problem about two infinite grounded planes with point charge in the middle. It's easy to...

My professor confused me today :( I'm trying to figure out the thickness of an anti reflection coating and it looks like from the equation 2ndcos(Θ) = mλ that for a given λ the thickness of the film should increase for incidence slightly away from normal. But he said that intuitively it...

ugh ... just took the test on the ETS website and got 31 T.T ... this is rather discouraging after all the work I've put into this studying for like 12 hours every day for the last month and a half ... maybe i do need a break -_- ... but the clock keeps ticking till the test day ... *sigh* ...

Oh, sorry for posting it in the wrong section >.<

I'm graduating on time. It's just that the physics classes in our school are offered every two years, so it so happens that quantum and classical both fell onto my last year here. If I knew I was going to do physics ahead of time (I started out as math major, now double majoring) I wouldn't...

just wondering how people did and what you did to study and prepare. I plan on taking the physics GRE this september, however i haven't taken any quantum or classical (analytical) mechanics yet. Unfortunately, both sequences start this September also :( But i don't want to wait till next year...

yes, i meant 12/37 X3 ... and also yes on km/sec :] also I'm a she >.> ... not that it matters <.< ...

oooooh, ok, thanks :3

I was just wondering if this problem is right and I'm missing something or ... http://www.astronomy.ohio-state.edu/~ryden/ast143/ps3_soln.pdf Cuz I'm reading the GRE book and it says here to use the relativistic Doppler shift formula. So the problem in the link would need to be solved like...

how about this one? "A meson is a bound state of a quark and an antiquark, both with spin 1/2. Which of the following is a possible value of total angular momentum j for a meson with orbital angular momentum l=2?" I've got the formula J=L+S. And I guess we can add or subtract the spins for a...

oooooh, geez, I wish the book would've stated that explicitly = -______- = thank you!

Ok, so for some reason this section of the GRE book makes 0 sense to me ... maybe because i haven't taken the class yet, maybe I'm missing something ... It says "If you have a spin-1 particle with m = +1 and a spin-1/2 particle with m = +1/2, then m_tot = +3/2 (this part makes sense, you just...

thanks, I'm going to need it X.X ... considering i have to take it this september, the same time the three-quarter quantum sequence starts ... -___________-

fair enough :P and no, no pokemons XD just "mew" as in the sound a kitty makes :3

what i typed up was the whole question ... i don't know what kind of assumptions are supposed to be made based on that information :\ ... maybe it's just poorly worded ...
