Question

Two energy levels of an electron in an atom are separated by 2 . 3 e V . The frequency of radiation emitted when the electrons go from higher to lower level is, 6.95 × 10 14 H z, 3.68 × 10 15 H z, 5.6 × 10 14 H z, 9.11 × 10 15 H z

Given, E 2 - E 1 = 2.3 e V Or ν = E 2 - E 1 h = 2.3 × 1.6 × 10 - 19 6.6 × 10 - 34 = 0.56 × 10 15 = 5.6 × 10 14 H z
