The energy levels of a hydrogen atom are shown below. The transition corresponding to emission of shortest wavelength is
Answer: (A) D
The shortest wavelength needs the largest energy gap. D ($3\to1$) releases $12.09\ \text{eV}$, far more than A ($0.66\ \text{eV}$), B ($2.55\ \text{eV}$) or C ($1.89\ \text{eV}$).
