line spectrum - a spectrum in which energy is concentrated at particular wavelengths; produced by excited atoms and ions as they fall back to a lower energy level spectrum - an ordered array of the components of an emission or wave
av MLA ABRAHAMSSON · 2001 · Citerat av 1 — Dissertation for the Degree of Doctor of Philosophy in Physical Chemistry presented the absorption spectrum of the acceptor and the fluorescence emission.
Line spectrum - produced when white light passes through hydrogen gas, it shows selected line frequencies. An absorption spectrum is produced. If high voltage is applied to the gas, an emission spectrum is produced. Hydrogen absorption and emission lines in the visible spectrum Emission lines refer to the fact that glowing hot gas emits lines of light, whereas absorption lines refer to the tendency of cool atmospheric gas to absorb the same lines of light. Later, additional lines were found in the ultraviolet and infrared regions of hydrogen's line spectrum. Soon Balmer's equation was extended to a more general one, called the Rydberg equation, which allows us to calculate the wavelengths of all the spectral lines … Line spectrum can also be generated in emission and absorption spectrum while continuous spectrum occurs when both absorption and emission spectra of a single species are put together.

Line spectra synonyms, Line spectra pronunciation, Line spectra translation, English dictionary definition of Line spectra. n. A spectrum produced by a luminous gas or vapor and appearing as distinct lines characteristic of the various elements constituting the gas. 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.

Atomic Structure multiple choice questions and answers covers MCQ questions on topics: Atoms, atomic spectrum, atomic absorption spectrum, atomic emission
With existing emission methods the intensity of a given spectrum line due to one particular concentration of an element in different materials varies greatly. For The line spectra of light-emitting atoms are uniquely characteristic for each specific chemical element, although they become increasingly complex for elements Ravi Divakaran, Ph. D. Chemistry & Science Different elements have distinctly different patterns in their line spectra, just like different people have different Nov 21, 2010 Hence only certain frequencies of light are observed, forming the emission spectrum, which is discrete bright coloured lines on a dark background You will be using a hand spectroscope to observe the difference between a continuous emission spectrum; produced by a fluorescent and a line spectrum;… Explain what a bright line spectrum is and how it is made. Our resources and materials support your teaching of chemistry to primary, secondary and higher wavelengths of the Balmer series of the hydrogen spectrum.

Line Spectrum: There are huge gaps between lines. Wavelength of the spectra; Continuous Spectrum: Continuous spectrum contains all the wavelengths of a given range. Line Spectrum: Line spectrum contains only a few wavelengths.
