The energy levels of an atom is shown is figure. Which one of these transitions will result in the emission of a photon of wavelength 124.1 ~nm ? Given ( h =6.62 10⁻³⁴ Js )

Options

  1. AB
  2. BA
  3. CC
  4. DD

Correct answer

D. D

Step-by-step solution

As E ( eV )= 1240 ( nm ) = 1240 124.1 10 eV Only is transition (D), the energy gap is 10 eV So, option (d) is correct
