The atomic hydrogen emits a line spectrum consisting of various series. Which series of hydrogen atomic spectra is lying in the visible region?
Show Hint
Recall which final energy level n defines each hydrogen series and where each falls in the electromagnetic spectrum.
Updated On: Nov 4, 2026
- Brackett series
- Balmer series
- Paschen series
- Lyman series
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The series of hydrogen are classified by the final level nf of the transition.
Lyman (nf = 1): ultraviolet.
Balmer (nf = 2): wavelengths about 656 nm to 365 nm, which lies in the visible region.
Paschen (nf = 3), Brackett (nf = 4): infrared.
Hence only the Balmer series lies in the visible region.
Answer: (2) Balmer series
Lyman (nf = 1): ultraviolet.
Balmer (nf = 2): wavelengths about 656 nm to 365 nm, which lies in the visible region.
Paschen (nf = 3), Brackett (nf = 4): infrared.
Hence only the Balmer series lies in the visible region.

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
