Finding Absorption Lines in Hydrogen Atom (n=10)

[dorts]

Could anyone help solve a problem how to find absorption lines in hydrogen atom from n=10 (n - principal quantum number). I know that not all quantum jumps of an electron in atom are possible, thus I don't know how many different emission lins will be from this energy level where n=10.

Have you learned about the selection rules?
