Emission and Absorption spectra of Hydrogen Atom
Emission Spectrum of Hydrogen
- When an electron in a hydrogen atom transitions from a higher energy level to a lower one, it releases energy in the form of light. The emitted light corresponds to specific wavelengths or colors.
- The hydrogen emission spectrum consists of a series of distinct and sharp lines in the visible and ultraviolet regions. These lines are called the Balmer series, and each line represents a particular electronic transition.
Absorption Spectrum of Hydrogen
- An absorption spectrum is created when a hydrogen atom absorbs light and undergoes electronic transitions from lower to higher energy levels. In this process, specific wavelengths of light are absorbed by the atom.
- The absorption spectrum of hydrogen, when examined against a continuous light source, shows dark lines or gaps at precisely the same wavelengths as the lines in the emission spectrum.

Difference Between Emission And Absorption Spectra
Difference Between Emission And Absorption Spectra: In spectroscopy, two types of spectra are used emission spectra and absorption spectra. The study of the interaction between matter and electromagnetic radiation is known as spectroscopy. The electromagnetic radiation spectrum produced when an electron changes from a high energy state to a lower energy state is known as the emission spectrum of a chemical element or chemical compound.
Spectra of both sorts offer information about the energy levels of molecules as well as atoms. When electrons absorb energy from their ground state to reach higher energy states, they emit light at frequencies with dark bands. The emission spectra of each element are distinct. Atoms absorb energy to create this kind of spectrum. They differ, however, in terms of how they are created and the information they give.
In this article, you will read about the difference between emission and absorption spectra, along with their definition, and the spectra of hydrogen atoms.
