(a) For Hydrogen atom, Bohr’s approximation to the energy ( En= -Z^2/n^2 13.6 ev) gives
results close to the experimental results. If the absorption spectrum of the H-atom
shows that the electron is excited from the ground state to 4TH excited state, calculate
the energy of the incident radiation.
(b) Once an electron gets excited its angular momentum changes. Calculate the change in
the orbital angular momentum for the above excitation process.
(c) Calculate the ground state energy and the ionization energy of the H-atom, using abovementioned
energy approximation.
