Energy of the Electron & Energy Levels question from MHT CET 2020 (19 Oct, Shift 2)

Q39MHT CET 2020 · 19 OCT · SHIFT 2Medium

Energy of the Electron & Energy Levels

The energy levels with transitions for the atom are shown. The transitions corresponding to emission of radiation of maximum and minimum wavelength are respectively

Show answer and solution

Answer: (d)

$\lambda = \frac{hc}{\Delta E}$ : max wavelength for smallest $\Delta E$ , min wavelength for largest $\Delta E$ .
A: $0 \to -2$ : 2 eV. B: $0 \to -4.5$ : 4.5 eV. C: $-2 \to -4.5$ : 2.5 eV. D: $-2 \to -10$ : 8 eV.
Smallest gap is A, largest is D.
So the answer is (d) A, D.
