continuous spectrum: a spectrum in which there are no absorption bands or lines. The perfect white light is a continuous spectrum over the visible region. Meaning of continuous spectrum. CONTINUOUS SPECTRUM A hot, glowing solid or liquid or a hot, glowing, dense gas produces a spectrum consisting of a continuous series of coloured bands ranging from violet on one end to red on the other (1).. continuous spectrum Spectrum in which the radiation is distributed over all frequencies, not just a few specific frequency ranges. A continuous spectrum is a spectrum in which all the wavelengths of the selected region have intensities. For a celestial body (such as a star or cloud of interstellar gas) which is in thermal equilibrium, the continuum emission approximates a blackbody spectrum, with a peak in emission at a wavelength determined by the object’s temperature. Hence, a continuous spectrum appears as a rainbow of all possible colors. Heat is the irregular motion of electrons, atoms, and molecules; the higher the temperature, the more rapid the motion. Continuous spectra occur on their own in nature given the right atmospheric conditions. Alternatively, you can use prisms to create continuous spectra. It must be noted that, in practice, it is virtually impossible to obtain a perfect continuous spectrum. A continuous spectrum is produced by light emitted by excited atoms. The colours of the rainbow, microwaves, ultraviolet radiation and x-ray are some examples. The continuous spectrum is due to bremsstrahlung, while the sharp peaks are characteristic X-rays associated with the atoms in the target. A spectrum is a set of wavelengths that is characteristic of electromagnetic radiation which is emitted or absorbed by a particular object, substance, atom or a molecule. There are three general types of spectra: continuous, emission, and absorption. Absorption lines are usually seen as dark lines, or lines of reduced intensity, on this continuous spectrum. The term is derived from the use of the word spectrum to describe the 'ghost-like' rainbow which appears when white light is shone through a clear scattering medium, such as water droplets or a prism. In the cse of sunlight the emitted photons are smoothly spread over a wide range of wavelengths. How to use spectrum in a sentence. For this reason, bremsstrahlung in this context is also called continuous X-rays. In physics, continuous spectrum refers to a range of values which may be graphed to fill a range with closely-spaced or overlapping intervals. Definition of continuous spectrum in the Definitions.net dictionary. Information and translations of continuous spectrum in the most comprehensive dictionary definitions resource on the web. Spectrum definition is - a continuum of color formed when a beam of white light is dispersed (as by passage through a prism) so that its component wavelengths are arranged in order. Continuous spectrum definition: a spectrum that contains or appears to contain all wavelengths but not spectrum lines... | Meaning, pronunciation, translations and examples The absorption spectra show only small black ranges where specific colors have been absorbed away. The shape of this continuum spectrum is approximately described by Kramers' law. It results from free electrons becoming bound to ions which then emit photons. Other articles where Continuous spectrum is discussed: electromagnetic radiation: Continuous spectra of electromagnetic radiation: Such spectra are emitted by any warm substance. A continuous spectrum is the presence of all wavelengths of visible light. The continuous spectrum shows a continuum of all the colors, whereas the emission spectra show only specific lines of emitted color. Main Difference – Continuous Spectrum vs Line Spectrum.
