Lyman spectral series is found in region of spectrum

Question

The wavelength of spectral line obtained in the spectrum of Li$^{2+}$ ion, when the transition takes place between two levels whose sum is 4 and difference is 2, is

Answer 1

Step 1: Hydrogen Spectral Series Review.
- Lyman series: electron transitions to $n=1$, high energy → ultraviolet.
- Balmer series: electron transitions to $n=2$ → visible light.
- Paschen, Brackett, Pfund series: electron transitions to $n=3,4,5$ → infrared.
Step 2: Summary.
Therefore, the Lyman series is located in the ultraviolet region of the electromagnetic spectrum.
Final Answer: \[ \boxed{\text{Ultraviolet}} \]

Lyman spectral series is found in region of spectrum
