Hence, a continuous spectrum appears as a rainbow of all possible colors. The electromagnetic radiation produced by this sudden deceleration of electrons is a continuous spectrum extending up… A gas under low pressure does not produce a continuous spectrum but instead produces a line spectrum, i.e., one composed of individual lines at specific frequencies characteristic of the gas, rather than a continuous band of all frequencies. German physicist Gustav Kirchoff (1824-1887) formulated these laws empirically during the mid-19th century. In an X-ray tube, electrons moving with an energy of E max = 10,000 to 50,000 eV (10–50 keV) are made to strike a piece of metal. A hot solid or hot, dense gas produces a continuous spectrum. …deceleration of the charges produces bremsstrahlung (“braking radiation”). Alternatively, you can use prisms to create continuous spectra. A continuous spectrum is produced by exciting atoms with electricity or radiation and the atoms of different elements give off radiation specific to the element. A continuous spectrum contains many different colors, or wavelengths, with no gaps. •A pool of molten iron •Lava flowing from a volcano. 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 can be produced by a luminous solid, liquid, or___ gas. A continuous spectrum source viewed through a cool, low-density gas produces an absorption-line spectrum. excited state: A state where the potential energy of the atom is higher than the ground state. White light for example can be dispersed by a prism to give a continuous spectrum in the optical region of the spectrum … atomic emission spectrum: The pattern of lines formed when light passes through a prism to separate it into the different frequencies of light it contains. •Examples where a continuous spectrum will be found: •An incandescent bulb. Continuous spectra occur on their own in nature given the right atmospheric conditions. cool. The continuous spectrum and the peaks of X-rays are produced from two processes: When fast-moving electrons emitted from the cathode are suddenly decelerated inside the target anode – these rays are called bremsstrahlung radiation, or “braking radiation”. Perfectly white light shined through a prism causes dispersion of the light, and we see a rainbow. Continuous spectra are produced by all incandescent solids and liquids and by gases under high pressure. AST 303: Chapter 13 1 Continuous Spectrum—Kirchoff’s First Law •A hot opaque substance (solid, liquid or gas) gives off a continuous spectrum, that is, a spectrum containing energy at all wavelengths. A hot, low-density gas produces an emission-line spectrum. continuous spectrum: All wavelengths of light are present. an absorption spectrum is produced when a___ gas lies in front of a source of continuous radiation. dense. A continuous spectrum is a spectrum in which all wavelengths are present between certain limits; it is produced by electrons undergoing free-bound transitions in a hot gas. A continuous spectrum is the presence of all wavelengths of visible light. light behaves both as a wave and as a___ particle ___ have the shortest wavelengths of any electromagnetic wave. Spectra are commonly produced using a single source of light whose dispersion in turn results in the formation of a continuous spectrum. Generally when gas is exposed to high pressures, they will produce continuous spectra but under lower pressures, either absorption or emission spectra are produced.
