In sample of hydrogen atomsin ground state, electron make transition f

1.	In sample of hydrogen atomsin ground state, electron make transition from ground state to particular excited state, where path length isfour times of debroglie wavelenght . Electrons make back transitiontothe ground state prouducing all possible photons.
Answer» WAVELENGHTOF photon used for this transition is 121.5 NM Final excitd state of `Li^(+2)`is 6 kinetic energy of electronin intaial excited state of `Li^(+2)`is 13.6 eV All are correct Solution :`3^(rd)` highest energetic photons`rArr(13.6-3.4)eV=10.2 eV`, transition is `2 to 1` `lambda=(hc)/(E)=(1240)/(10.2)nm=121.5nm` For H atoms =gor `Li^(+)`ION `13.6xx1[1-(1)/(2^(2))]=13.6xx9[(1)/(3^(2))-(1)/(6^(2))]` `therefore`for `Li^(+)`ion transition is `3 to 6` Initial excited state=3 Final excited state =6 K.E. ofelectronin intial excited state of `Li^(+2)`=`13.6xx(3^(3))/(3^(3))`=`13.6 eV`.
