Question

Which of the following series of transitions in the spectrum of hydrogen atoms fall in the visible region?

• A. Lyman series
• B. Brackett series
• C. Balmer series
• D. Paschen series

Answer 1

The correct option is C

Balmer series

Explanation for the correct options:

(C)Balmar series

• Balmar series falls under the visible region in the hydrogen spectrum.
• Spectral emission takes place when electron transitions take place from a high-energy level to a lower energy level of $n_1=2$ energy state.

Explanation for the incorrect options :

(A)Lyman series

• The Lyman series wavelength falls in the ultraviolet band and this is displayed when the electron transition takes place from higher energy states to $n_1=1$ energy state.

(B)Brackett series

• In the Brackett series, the wavelength falls in the Infrared region of the electromagnetic spectrum and this is displayed when the electron transition takes place from higher energy states to $n_1=4$ energy state.

(D)Paschen series

• The Paschen series wavelength falls in the Infrared region of the electromagnetic spectrum and this is displayed when the electron transition takes place from higher energy states to $n_1=3$ energy state.

Hence, option (C) is correct, Balmer series transitions in the spectrum of hydrogen atoms fall in the visible region.
