Balmer Series For Hydrogen
The Balmer family of hydrogen
Hydrogen is the lightest and most widely distributed element in the universe. The wonders of its spectrum are valued by all scholars, and the Balmer family is especially outstanding among them.
In the past, scholars studied the hydrogen spectrum and saw that its spectral lines could be followed. Balmer carefully explored and finally found a way to solve the secret of the specific spectral lines of the hydrogen spectrum, which is the Balmer family.
The spectral lines involved in the Balmer family are caused by the transition of hydrogen atoms from high energy levels to second energy levels. The number of wavelengths can be expressed in a formula: $\ frac {1} {\ lambda} = R_H (\ frac {1} {2 ^ {2}} -\ frac {1} {n ^ {2}}) $, $n = 3,4,5,\ cdots $. In the formula, $\ lambda $is the wavelength, and $R_H $is the Rydberg constant. Its value is accurate and is the cornerstone of spectral research.
When $n = 3 $, a line of hydrogen spectrum is obtained, the color is red, and its light is soft and bright. $n = 4 $, and another line is obtained, and the color gradually turns blue. As the value of $n $increases, the spectral lines become more and more dense, converging to the shortwave end.
The Balmer system is of great significance to physics. First, to prove the quantization of atomic energy levels. The energy levels of hydrogen atoms are discrete and non-continuously variable, which is very different from classical physics. Second, it is the basis of the theory of atomic structure. Helpers explore the internal structure of atoms and understand the laws of electron motion. Third, it is also useful in astrophysics. Looking at the spectrum of stars, if you see the Balmer line, you can infer that the star contains hydrogen, and know its temperature and density.
The Balmer system, such as opening the door to the spectrum of hydrogen atoms, allows scholars to see the wonders of the microscopic world, which is very useful for the progress of science.
