MCQ
In the above figure $D$ and $E$ respectively represent
  • ✓
    Absorption line of Balmer series and the ion ization potential of hydrogen
  • B
    Absorption line of Balmer series and the wavelength lesser than lowest of the Lyman series
  • C
    Spectral line of Balmer series and the maximum wavelength of Lyman series
  • D
    Spectral line of Lyman series and the absorption of greater wavelength of limiting value of Paschen series
✓

Answer

Correct option: A.
Absorption line of Balmer series and the ion ization potential of hydrogen
$D$ is excitation of electron from $2$ orbit corresponding to absorption line in Balmer series and $E$ is the energy released to bring the electron from $\infty$ to ground state i.e. ionisation potential.
