The spectroscopic image of the gaseous hydrogen atom shows the emission spectrum of the hydrogen atom. This spectrum contains lines of light of specific wavelengths emitted by the hydrogen atom, depending on its energy levels. The spectrum of the hydrogen atom consists of different series such as Balmer series, Lyman series, Paschen series and Brackett series. These series represent the wavelengths of light emitted by the electron of the hydrogen atom as it passes through different energy levels. This spectrum is used to study the internal structure of the hydrogen atom and the energy levels between electrons. It is also an important tool in astronomy because it can be used to determine the composition and temperature of stars.
