comment Calculation of magnetic force magnitude from a parmenant magnet
What's vertical pull? What units do they give you for that? Can you link the website?

comment Effect of slits and a lens
Ok, thank you, that: $x=f\sin \theta$ was what I needed, I was using $x$ as a generic variable, meaning angular coordinates: $\mathrm{sinc} ^2(kpd/2)$. Thanks for your help.

comment Effect of slits and a lens
Thank you for your answer, specially the third case. So, the lens still compresses the difraction pattern of the $\sin^2 x/x^2$, doesn't it? i understand they're centered at the same point, but is there a way to calculate quantitatively the position of the fringes in the focal plane of the lens?

comment Historic derivation of Wien's law
@LeosOndra I would appreciate it, I don't spek any russian though. I'm not interested in the whole article, only in the derivation of that law.
