Line spectrum definition in chemistry
A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules. These "fingerprints" can be compared to the previously collected ones of atoms and molecules, and are thus used to id… NettetEmission spectra or line spectra. The spectrum of bright lines, bands, or continuous radiation characteristic of and determined by a specific emitting substance subjected to a specific kind of excitation is called as spectra. When radiation is emitted, lines are obtained, it is called as emission spectra.

When matter is very hot it emits light. This light, when seen through a...
Nettet21. sep. 2024 · 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 ).
NettetLine 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. Each element produces a unique set of spectral lines. NettetThe 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 …

NettetSpectral theory is connected with the investigation of localized vibrations of a variety of different objects, from atoms and molecules in chemistry to obstacles in acoustic waveguides. These vibrations have frequencies , and the issue is to decide when such localized vibrations occur, and how to go about computing the frequencies. mochilas targus chileNettetThe spectrum of radiation emitted by an atom is called emission spectrum. In contrast to the continuous spectrum of white light, an emission spectrum is usually discontinuous with dark spaces between the bright lines, called line spectrum. mochila star wars rodinhaNettetThe spectrum with the smaller effective bandwidth has a better resolution, allowing us to see the presence of three peaks, but at the expense of a noisier signal.
