line spectrum quizlet

For each absorption line spectrum, the short wavelengths of light (or blue end) of the electromagnetic spectrum are shown on the left side and the long wavelengths of light (or red end) of the spectrum are shown on the right side. An absorption spectrum occurs when light of all wavelengths passes through a cold, dilute gas and atoms in the gas absorb at characteristic frequencies. As the re-emitted light is unlikely to be emitted in the same direction as the absorbed photon, this gives rise to dark lines (absence of light) superimposed on the continuous spectrum. For example, when a high-voltage electrical discharge is passed through a … Recommended Videos . Absorption spectra. In star: Line spectrum. Continuous spectrum is a spectrum having all the wavelengths within a given limit whereas line spectrum is a spectrum having some lines of wavelengths within a given limit. In Stokes lines Such kind of spectra is known as atomic spectra or line spectra. A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Line Spectra. A spectral line is like a fingerprint that can be used to identify the atoms, elements or molecules present in a star, galaxy or cloud of interstellar gas.If we separate the incoming light from a celestial source using a prism, we will often see a spectrum of colours crossed with discrete lines. top. Discover free flashcards, games, and test prep activities designed to help you learn … An absorption spectrum is like a photographic negative of an emission spectrum. Although objects at high temperature emit a continuous spectrum of electromagnetic radiation, a different kind of spectrum is observed when pure samples of individual elements are heated. Spectral lines are produced by transitions of electrons within atoms or ions. Heavy Metals In Water. Analyzing spectra: 2 points each The absorption line spectra for six hypothetical stars, each with different temperatures, are shown below. For observing the absorption spectrum, electromagnetic radiations are bombarded on a sample that absorbs radiation of certain wavelengths. The nucleus Emission Spectrum & Absorption Spectrum. Other articles where Line spectrum is discussed: spectroscopy: Basic atomic structure: The emission and absorption spectra of the elements depend on the electronic structure of the atom. An atom consists of a number of negatively charged electrons bound to a nucleus containing an equal number of positively charged protons. Define line spectrum. Balmer lines are historically referred to as "H-alpha", "H-beta", "H-gamma" and so on, where H is the element hydrogen. Four of the Balmer lines are in the technically "visible" part of the spectrum, with wavelengths longer than 400 nm and shorter than 700 nm. Quizlet is a lightning fast way to learn vocabulary. n. A spectrum produced by a luminous gas or vapor and appearing as distinct lines characteristic of the various elements constituting the gas. As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed.… Read More; Stokes lines. line spectrum synonyms, line spectrum pronunciation, line spectrum translation, English dictionary definition of line spectrum.
