Electron in hydrogen atom first jumps from third excited state to second excited state and then from second excited to the first excited state. The ratio of the wavelengths &lambda;1:&lambda;2 emitted in the two cases is ans; 1st the electron jumps from 3rd excited state to the 2nd ie from n=4 to n=3 then 1/&lambda;1 =R(1/n12 -1/n22 )= R ( 1/9 &ndash; 1/16) =R (7/144) similarly 1/&lambda;2 = R ( &frac14; &ndash; 1/9 )=R(5/36) &there4; &lambda;1/&lambda;2 = 1/R(144/7) * R (5/36) =4*5/7 =20/7 so the ans is 20/7
