comment Light dispersion in water
So if I incide light not normally in a big amount of water, will I see dispersion? Shouldn't then I see dispersion by looking at the sun (when it's NOT on top of the sky) from behind the water, for example in the sea?

comment Decomposition of this wave function in eigenfunctions
Thank you for your help. That's what I initially thought, but he made some reasoning before calculating, and doing that in the case when the highest value for $\ell$ is, let's say, $10$, doesn't seem very efficient.

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?
