What is the reason for Paschen series in hydrogen spectrum?
What is the reason for Paschen series in hydrogen spectrum?
Paschen series is displayed when electron transition takes place from higher energy states(nh=4,5,6,7,8,…) to nl=3 energy state. All the wavelength of Paschen series falls in the Infrared region of the electromagnetic spectrum. The shortest wavelength of next series, i.e., Brackett series overlap with Paschen series.
Is Lyman only for hydrogen?
The series is named after its discoverer, Theodore Lyman, who discovered the spectral lines from 1906–1914. All the wavelengths in the Lyman series are in the ultraviolet band….Lyman series (n′ = 1)

Is Balmer series only for hydrogen?
The Balmer series, or Balmer lines in atomic physics, is one of a set of six named series describing the spectral line emissions of the hydrogen atom. After Balmer’s discovery, five other hydrogen spectral series were discovered, corresponding to electrons transitioning to values of n other than two .
How are Balmer and Paschen series originated in hydrogen spectra?
We get Balmer series of the hydrogen atom. It is obtained in the visible region. Paschen Series: If the transition of electron takes place from any higher orbit (principal quantum number = 4, 5, 6, …) to the third orbit (principal quantum number = 3).
What is the difference between Lyman and Balmer series?
Lyman and Balmer series are hydrogen spectral line series that arise from hydrogen emission spectra. 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.
What is the shortest wavelength in Brackett series?
The shortest wavelength of the Brackett series of a hydrogen-like atom (atomic number Z) is the same as the shortest wavelength of the Balmer series of hydrogen atoms.
What is the shortest wavelength of Lyman series?
91.2 text nm
The shortest wavelength in Lyman series is 91.2 text nm .
What is the shortest wavelength of Balmer series?
364 nm
Since 1˜ν=λ in units of cm, this converts to 364 nm as the shortest wavelength possible for the Balmer series.
What is the longest wavelength in the Balmer series?
656 nm
Question: What is the longest wavelength in the Balmer series? The answer is 656 nm but need to know how to get the answer.
What is the shortest wavelength of Paschen series?
Therefore, 8.21×10−7m is the shortest wavelength in the Paschen series of spectral lines.
Where to find Paschen series in hydrogen spectrum?
Different lines of Balmer series area l If the transition of electron takes place from any higher orbit (principal quantum number = 4, 5, 6, …) to the third orbit (principal quantum number = 3). We get Paschen series of the hydrogen atom. It is obtained in the infrared region.
What are the spectral lines of the Balmer series?
Balmer series is a hydrogen spectral line series that forms when an excited electron comes to the n=2 energy level. 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.
How is the Balmer series of a hydrogen atom obtained?
We get Balmer series of the hydrogen atom. It is obtained in the visible region. This formula gives a wavelength of lines in the Balmer series of the hydrogen spectrum.
How is the Lyman series different from the Balmer series?
The Lyman series is in the ultraviolet while the Balmer series is in the visible and the Paschen, Brackett, Pfund, and Humphreys series are in the infrared. In 1914, Niels Bohr proposed a theory of the hydrogen atom which explained the origin of its spectrum and which also led to an entirely new concept of atomic structure.
