Hydrogen Emission and Absorption Spectrum
The emission and absorption spectra of hydrogen
The emission and absorption spectra of hydrogen are the key to the exploration of physics. In the past, Zhu Xian dedicated himself to this, in order to understand the secrets of the microscopic.
Looking at the emission spectra of hydrogen, when a hydrogen atom is excited by energy, its electrons move to a higher energy level. However, this state is unstable, and the electrons immediately fall back to the lower energy level, and release energy in the form of photons. The frequencies of the photons are different, so they form discrete spectral lines. The distribution of this spectral line follows a specific law, revealing the essence of the quantization of the microscopic world.
Balmer has summed up an exquisite formula for the visible region spectral lines of the hydrogen emission spectrum. The formula can accurately predict the wavelength of the spectral line, laying the foundation for exploring the hydrogen spectrum. Thanks to this, scholars have been able to understand the structure of the energy levels of hydrogen atoms, and the energy difference between the energy levels is exactly the same as the energy of the emitted photons.
As for the absorption spectrum of hydrogen, it is when the light of the continuous spectrum irradiates the hydrogen atom. If the photon energy matches the difference between the energy levels of the hydrogen atom, the hydrogen atom absorbs this photon, and the electron jumps to a high energy level. Therefore, on the continuous spectrum, the dark absorption line corresponds to the spectral line of the emission spectrum one by one.
The emission and absorption spectra of hydrogen are like a key, opening the door to the microscopic world. Helping our generation understand the mysteries of atomic structure and energy level transition, and providing a foundation for the development of quantum mechanics, with far-reaching impact and great merit.
