Concept explainers
Interpretation:
Wavelength of the first five lines in Pickering series has to be calculated and also the region in which they occur has to be given.
Explanation of Solution
Ionization energy can be calculated using the equation given by Bohr that is shown below.
Where,
It is said that the electron fall to
Wavenumber of any line that is present in visible spectrum of hydrogen is shown by Balmer and it can be given by using the formula shown below;
In the above equation,
Wavelength of first five lines of Pickering series:
First line:
Atomic number of helium is
Second line:
Atomic number of helium is
Third line:
Atomic number of helium is
Fourth line:
Atomic number of helium is
Fifth line:
Atomic number of helium is
The wavelength of the first five lines of Pickering series is summarized as shown below;
Wavelength ( |
From the wavelength, it is found that this series lies in visible region of the electromagnetic spectrum.
In solar astronomy, this series is used n calculation of the properties of stars, age, luminosity, velocity, etc.
