Using Bohr's postulates, obtain the expressions for (i) kinetic energy and (ii) potential energy of the electron in stationary state of hydrogen atom. Draw the energy level diagram showing how the transitions between energy levels result in the appearance of Lymann Series. |

Answer» Solution :This series is produced when ELECTRON jumps from higher orbits to the first STATIONARY orbit (i.e., `n_(F) =1`).Thus, for this series. `bar(v) =(1)/(lambda)=R((1)/(l^(2)) -(1)/(n_(i)^(2)))` `therefore " where"n_(i)=2, 3, 4, 5...` For the longest wavelength of Lyman Series `n_(i)=2.`
