Question

The energy levels of a hypothetical atom are shown below. Which of the shown transitions will result in the emission of a photon of wavelength 275nm? 

Which of these transitions correspond to emission of radiation of (i) maximum and (ii) minimum wavelength?

Answer 1

Energy of photon wavelength 275nm

This corresponds to transition ‘B’.

For maximum wavelength ΔE should be minimum. This corresponds to transition A. 

(ii) For minimum wavelength ΔE should be maximum. This corresponds to transition D.
