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

- A A, D
- B B, C
- C C, D
- D A, C
Answer & Solution
Correct Answer
(A) A, D
Step-by-step Solution
Detailed explanation
(D)
Energy \(\quad \mathrm{E}=\frac{\mathrm{hc}}{\lambda} \quad \therefore \mathrm{E} \propto \frac{1}{\lambda}\)
In transition A, change in energy is minimum, hence wavelength is maximum. In transition D, Change in energy is maximum, hence wavelength is minimum.
Energy \(\quad \mathrm{E}=\frac{\mathrm{hc}}{\lambda} \quad \therefore \mathrm{E} \propto \frac{1}{\lambda}\)
In transition A, change in energy is minimum, hence wavelength is maximum. In transition D, Change in energy is maximum, hence wavelength is minimum.
