Hey guys, have this question for my 1st year exams.
The visible spectrum obtained from a hydrogen discharge tube consists of four
lines at 410,434 nm, 486 nm, and 656 nrn. These lines reflect emissions of
photons by electrons in excited states falling to the quantum level with a principal
quantum number of 2.
Using these data calculate the Bohr constant for the hydrogen atom, and identify
the initial principal quantum number involved in the generation of each of the
given spectral lines.
Cannot figure this one out at all. Any help much appreciated! Thanks.
