The hydrogen spectrum has six series. They are Lyman series, Balmer series, Paschen series, Brackett series, Pfund series, and Humphreys series. This presentation discusses the longest and shortest wavelengths of spectral lines that occur in all the six series of the hydrogen spectrum.

2. Name the series of the hydrogen
spectrum
The hydrogen spectrum has six series
named by the scientists who discovered
them. They are the sequence of spectral
emissions arranged based on their
wavelengths in the electromagnetic region
of the hydrogen atomic spectrum. The
names of those six hydrogen spectrum
series are;
Lyman series
Balmer series
Paschen series
Brackett series
Pfund series
Humphrey’s series

3. LYMAN SERIES
This series of spectral lines were
observed during electron
transition from higher stationary
orbits to the first orbit of the
hydrogen atom and named after
the discoverer Theodore Lyman.
And it occurs in the ultraviolet
region of the electromagnetic
spectrum. The longest and
shortest wavelengths of the Lyman
series are 121 nm and 91 nm.
Hence, the limits of the Lyman
series are 91nm and 121nm

4. BALMER SERIES
This series of spectral lines
were observed during electron
transition from higher
stationary orbits to the second
orbit of the hydrogen atom and
named after the discoverer
Johann Jakob Balmer. And it
occurs in the visible region of
the electromagnetic spectrum.
The longest and shortest
wavelengths of the Balmer
series are 656 nm and 365 nm.

5. PASCHEN SERIES
This series of spectral lines were
observed during electron transition
from higher stationary orbits to the
third orbit of the hydrogen atom and
named after the discoverer Friedrich
Paschen. And it occurs in the near
infrared region of the
electromagnetic spectrum.
The longest and shortest
wavelengths of the Paschen series
are 1875 nm and 821 nm.

6. BRACKETT SERIES
This series of spectral lines were
observed during electron transition
from higher stationary orbits to the
fourth orbit of the hydrogen atom
and named after the discoverer
Frederick Sumner Brackett. And it
occurs in the infrared region of the
electromagnetic spectrum. The
longest and shortest wavelengths of
the Brackett series are 4051 nm and
1458 nm.

7. PFUND SERIES
This series of spectral lines were
observed during electron transition
from higher stationary orbits to the
fifth orbit of the hydrogen atom and
named after the discoverer August
Herman Pfund. And it occurs in the
far infrared region of the
electromagnetic spectrum. The
longest and shortest wavelengths of
the Pfund series are 7460 nm and
2280 nm.

8. HUMPHREYS SERIES
This series of spectral lines were
observed during electron transition
from higher stationary orbits to the
sixth orbit of the hydrogen atom and
named after the discoverer Curtis
Judson Humphreys. And it occurs in
the far infrared region of the
electromagnetic spectrum. The
longest and shortest wavelengths of
the Humphreys series are 12.37 μm
and 3.282 μm.
