comment Constant quantity associated to symmetry
@bechira I am uncomfortable with stating that as some kind of theorem. I'd expect some kind of relevant content, plus I know how Noether conserved charges come out from symmetries, and I was expecting to see a connection.

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.
