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 …
6.3: Atomic Line Spectra and the Bohr Equation - Chemistry ...
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).
Emission spectrum - Wikipedia
The spectrum appears in a series of lines called the line spectrum. This line spectrum is called an atomic spectrum when it originates from an atom in elemental form. Each element has a different atomic spectrum.
Line Spectra | CIE A Level Physics Revision Notes 2022
2022年5月25日 · Revision notes on 22.3.2 Line Spectra for the CIE A Level Physics syllabus, written by the Physics experts at Save My Exams.
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
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.
6.3: Line Spectra and the Bohr Model - Chemistry LibreTexts
Atoms of individual elements emit light at only specific wavelengths, producing a line spectrum rather than the continuous spectrum of all wavelengths produced by a hot object. Niels Bohr explained the line spectrum of the hydrogen atom by assuming that the electron moved in circular orbits and that orbits with only certain radii were allowed.
