a gas of identical hydrogen like atoms has some atoms in the lowest energy levelA and some atoms in a particular upper energy level B and there are no atoms in any other energy level.the atomjs of the gas makes transtition to highest level by absorbing light of photon energy 2.7 e.v .subsquiently, the atoms emits radiations of only six different photons energy.some of the emmited photon have energy 2.7ev , some have energy more and some have less than 2.7ev a) Find the principal quantum no. of initially excited level B.b) Find the ionisation energy for the gas atoms.c)find the maximum minimum energy of the emitted photons.
