A hydrogen atom in ground state is given an energy of 10.2 eV. How many spectral lines will be emitted due to transition of electrons? (a) 3 (b) 6 (c) 10 (d) 1

Answer: (d). E = -13.6 + 10.2 = -3.4 eV = E₂, so the atom goes to n = 2. From n = 2 only one transition ( 2→1) is possible. So the answer is (d) 1.
