Q. In a sample of H-atoms, electrons de-excite from a level $n$ to 1 . The total number of lines belonging to Balmer series are $2 .$ If the electrons are ionised from level $n$ by photons of energy $13 eV$, then the kinetic energy (in $eV$ ) of the ejected photoelectrons will be

Solution:

$n=4$ and energy of $4^{\text {th }}$ orbit is $-0.85 eV$
