Question

In an atom, when an electron jumps from higher energy level to lower energy level, it emits energy in the form of

electromagnetic radiations. When these electromagnetic radiations are passed through a prism and received on a

photographic film, some lines are observed and those lines are called spectral lines. For hydrogen like species when

jump takes from any excited state to ground state (n = 1), lines produced in that case are called Lyman series. If

transition occurs from third or above levels to second level, then corresponding lines are called Balmer series. Similarly

for next levels, these are called Paschen series, Brackett series and Pfund series respectively.

1. In a gaseous sample, 3 atoms of hydrogen like species are present in fourth excited state. Calculate the maximum

number of different spectral lines that can be produced when all the atoms come to ground state

2. In a gaseous sample, 3 atoms of hydrogen like species are present in second, third and fourth excited states

respectively. Calculate the maximum number of different Balmer lines that can be produced when all the atoms

come to ground state.

4. In a gaseous sample, 3 atoms of hydrogen like species are present in second, third and fourth excited state

respectively. Calculate the maximum number of different spectral lines that can be produced when all the atoms

come to ground state.

5. If there is only atom of hydrogen like species in fourth excited state then what will be the maximum and minimum

number of spectral lines produced when atom comes to ground state?
