Question

In the figure below, D and E respectively represent

Options

• Absorption line of Balmer series and the ionization potential of hydrogen.

• Absorption line of Balmer series and the wavelength lesser than lowest of the Lyman series.

• Spectral line of Balmer series and the maximum wavelength of Lyman series.

• Spectral line of Lyman series and the absorption of greater wavelength of limiting value of Paschen series.

Answer 1

Absorption line of Balmer series and the ionization potential of hydrogen.

Explanation:

D is excitation of electron from 2^nd orbit corresponding to absorption line in Balmer series and E is the energy released to bring the electron from ∞ to ground state i.e., ionisation potential.
