There are emission and absorption lines . The emission spectrum of a chemical element or compound is the 'range' of frequencies of electromagnetic radiation (emitted by an atom or molecule passing from a high energy state (excited state) to a lower one or configuration with less energy).

Sep 27, 2005 In fact, we can learn a great deal, not only about the chemical Molecules also produce spectral lines, but their spectra are much more

Previous Next. Hydrogen Spectrum : If an electric discharge is passed through hydrogen gas is taken in a discharge tube under low pressure, and the emitted radiation is analysed with the help of spectrograph, it is found to consist of a series of sharp lines in the UV, visible and IR regions. This series of lines is known as line or atomic You posted a picture of a hydrogen spectrum from a discharge tube which consists of discrete lines in the UV, visible, and IR regions. In the same way, the hydrogen-air flame has an emission in the ultraviolet, visible and in the IR. The blue flame is not a line spectrum, as you might speculate.

To learn more about hydrogen emission spectrum download BYJU’S – The Learning App. Read more: Emission spectrum and atomic spectra; Spectroscopy Hydrogen spectrum is an example of line emission spectrum or atomic emission spectrum. (a) When an electric discharge is passed through hydrogen gas at low pressure, a bluish light is emitted. (b) This light shows discontinuous line spectrum of several isolated sharp lines through prism. (c) All these lines of H-spectrum have Lyman, Balmer, Paschen, Barckett, Pfund and Humphrey series. 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. Lines in the spectrum were due to transitions in which an electron moved from a higher-energy orbit with a larger radius … In spectrum …other hand, is called a line spectrum because only a few wavelengths are emitted. These wavelengths appear to be a series of parallel lines because a slit is used as the light-imaging device.

When its electron jumps from higher energy level to a lower one, it releases a photon. Those photons cause different colours of light of different wavelengths due to the different levels.

Emission spectrum from a Cu hollow cathode lamp.

n. A spectrum produced by a luminous gas or vapor and appearing as distinct lines characteristic of the various elements constituting the gas. Brightline spectrum definition, the spectrum of an incandescent substance appearing on a spectrogram as one or more bright lines against a dark background. See more.

The intensity of the absorption varies as a function of frequency, and this variation is the absorption spectrum. 2008-11-09 2015-11-03 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. Lines in the spectrum were due to transitions in which an electron moved from a higher-energy orbit with a larger radius to a lower-energy orbit with smaller radius.
