6.3: Atomic Line Spectra and the Bohr Equation
When the emitted light is passed through a prism, only a few narrow lines of particular wavelengths, called a line spectrum, are observed rather than a continuous range of wavelengths (Figure 6.3.1).
6.3: Atomic Line Spectra and Niels Bohr - Chemistry LibreTexts
Line Spectra. There are two types of line spectra, emission and absorption. In an emission spectra electrons are excited to an excited state by thermal or electrical means and then relax back to a lower state and emit a photon of light at a specific energy, which is …
What is a line spectrum and how is it produced? - Physics Network
2023年5月20日 · Line spectra is a phenomenon which occurs when excited atoms emit light of certain wavelengths which correspond to different colours. The emitted light can be observed as a series of coloured lines with dark spaces in between. These series of coloured lines are called line or atomic spectra.
2016年10月3日 · This article outlines the main concepts of atomic structure, with some emphasis on terminology and notation. Atomic radiation is discussed, in particular the wavelengths, intensities, and shapes of spectral lines, and a few remarks are made regarding continuous spectra. We include updated tabulations of
3.3 Atomic Line Spectra | Chemistry I - Mississippi State University
3.3 Atomic Line Spectra. The emission spectrum of a substance can be seen by energizing a sample of material with some form of energy. The “red hot” or “white hot” glow of an iron bar removed from a fire is the visible portion of its emission spectrum.
Bohr’s Model: Line Spectra | Pathways to Chemistry
If hydrogen gas is placed into a discharge tube, and a high voltage is applied, the result is 4 different colored lines. This is called a line spectrum which consists of radiation of specific wavelengths. The spectrum is not continuous and only has four different colors.
4: Atomic spectra, simple models of atoms - Physics LibreTexts
Quantum mechanics had initially the aim to explain the line spectra of atoms seen in optical spectroscopy. Later on it became a fundamental theory explaining all the microscopic phenomena including molecular-, solid state-, nuclear-, and high energy particle physics. Figure 4.1: Emission and absorption spectra of the Balmer series of hydrogen.
