In which region Lyman and Paschen series are appeared?
The Lyman series lies in the ultraviolet, whereas the Paschen, Brackett, and Pfund series lie in the infrared.
Does Balmer and Paschen series overlap?
(C) No 2 series (e.g. Lyman, Balmer, Paschen etc.) overlap with each other, i.e. lowest frequency of one series will be greater than highest frequency of the next series.
What is Lyman series in physics?
Lyman series (nl=1) The series was discovered during the years 1906-1914, by Theodore Lyman. Thus it is named after him. According to Bohr's model, Lyman series is displayed when electron transition takes place from higher energy states(nh=2,3,4,5,6,…) to nl=1 energy state.
How are Balmer series and Paschen series originated in hydrogen spectra?

What is Lyman Series?
Lyman series is a hydrogen spectral line series that forms when an excited electron comes to the n=1 energy level. And, this energy level is the lowest energy level of the hydrogen atom. The formation of this line series is due to the ultraviolet emission lines of the hydrogen atom.
What is the Difference Between Lyman and Balmer Series?
The key difference between Lyman and Balmer series is that Lyman series forms when an excited electron reaches the n=1 energy level whereas Balmer series forms when an excited electron reaches the n=2 energy level. Some lines of blamer series are in the visible range of the electromagnetic spectrum. But, Lyman series is in the UV wavelength range.
What is the transition of an excited electron from n=2 to n=1?
Moreover, we can name each transition using Greek letters; the transition of an excited electron from n=2 to n=1 is Lyman alpha spectral line, from n=3 to n=1 is Lyman beta, and so on. The physicist Theodore Lyman found the Lyman series in 1906.

For the lines in the Lyman series, the names are as Lyman alpha, Lyman beta and so on whereas for the lines in the Balmer series the names are as H-alpha, H-beta, etc. Below infographic summarizes the difference between Lyman and Balmer series.
What is the wavelength of the Balmer series?
Further, this series shows the spectral lines for emissions of the hydrogen atom, and it has several prominent ultraviolet Balmer lines having wavelengths that are shorter than 400 nm. Balmer series is calculated using the Balmer formula, which is an empirical equation discovered by Johann Balmer in 1885.
What does H stand for in spectral lines?
The letter “H” stands for “hydrogen”. When considering the wavelengths, the first spectral line is in the visible range of the electromagnetic spectrum. And, this first line has a bright red colour.

Which atom produces the simplest series of images?
Hydrogen atom is the simplest atomic system found in nature, thus it produces the simplest of these series. When the beam of light or any radiation is made to enter the device through a slit, each individual component of the light or radiation form images of the source. These images can be visualised when resolved under the spectroscope.
