Line Spectra | CIE A Level Physics Revision Notes 2022 - Save My …
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.
What is a line spectrum and how is it produced? - Physics Network
May 20, 2023 · A spectral line is a spectrum in which light of only a certain wavelength is emitted or absorbed, rather than a continuous range of wavelengths, rather than a continuous range of colours. Spectral lines are highly atom-specific, and can be used to identify the chemical composition of any medium.
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.
Line Spectra | Mini Physics - Free Physics Notes
The emitted light are analyzed with a spectrometer and discrete bright lines in a dark background are observed. The well-defined separation of lines is experimental evidence for the existance of separate or ‘quantized’ energy levels in the atom. No …
2.6: Lines Spectra- Emission and Absorption Lines
Learning Objectives. You will be able to distinguish between emission and absorption lines in a spectrum. You will know how spectral lines are produced. You will be able to calculate the energy/frequency/wavelength of a photon absorbed or emitted by a hydrogen atom.
5.5: Formation of Spectral Lines - Physics LibreTexts
Apr 10, 2022 · Explain how emission line spectra and absorption line spectra are formed; Describe what ions are and how they are formed; Explain how spectral lines and ionization levels in a gas can help us determine its temperature; We can use Bohr’s model of the atom to understand how spectral lines are formed.
Line Spectrum - Introduction, Types, Broadening, and Shift
A spectral line is defined as a dark or bright line in an otherwise continuous and uniform spectrum, resulting from light’s absorption or emission in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used in the identification of molecules and atoms.

Line Spectra - an overview | ScienceDirect Topics
Line spectra refer to the emission or absorption spectra of incandescent gases, characterized by a series of sharp lines in the spectrum. These lines are specific to chemical elements and can be used to identify the presence of a particular element.
