Question:

The energy levels of the hydrogen spectrum is shown in figure. There are some transitions A, B, C, D and E. Transition A, B and C respectively represent.

Options:

First member of Lyman series, third spectral line of Balmer series and the second spectral line of Paschen series

Ionization potential of hydrogen, second spectral line of Balmer series and third spectral line of Paschen series

Series limit of Lyman series, third spectral line of Balmer series and second spectral line of Paschen series

Series limit of Lyman series, second spectral line of Balmer series and third spectral line of Paschen series

Correct Answer:

Series limit of Lyman series, third spectral line of Balmer series and second spectral line of Paschen series

Explanation:

Transition A (n = ∞ to 1) : Series limit of Lyman series

Transition B (n = 5 to n = 2) : Third spectral line of Balmer series

Transition C (n = 5 to n = 3) : Second spectral line of Paschen series
