In sample of hydrogen atoms in ground state, electron make transition

1.	In sample of hydrogen atoms in ground state, electron make transition from ground state to particular excited state, where path length is four times of debroglie wavelenght . Electrons make back transition to the ground state prouducing all possible photons. Ve,cocity of electron in fianal excited dtate in the above sample of hydrogen atom isA. `(2.18xx10^(6))/4m//s`B. `(2.18xx10^(6))/8m//s`C. `(2.18xx10^(6))/2m//s`D. None of these
Answer» Correct Answer - A `2pir_(n)=nlambda=4lambda rArrn=4` `V=2.18xx10^(6)(z)/(n)m//s=(2.18xx10^(6))/(4)m//s`
