Why do heated bodies produce continuous spectra?

WebMay 29, 2024 · The emission spectrum of a body or substance is the characteristic range of radiations it emits when it is heated, bombarded by electrons or ions, or absorbs photons. The absorption spectrum of a substance is produced by examining, through the substance and through a spectroscope, a continuous spectrum of radiation. WebSep 8, 2024 · When the emitted light is passed through a prism, only a few narrow lines, called a line spectrum, which is a spectrum in which light of only a certain wavelength is emitted or absorbed, rather than a continuous range of wavelengths (Figure 6.3. 1 ), rather than a continuous range of colors. WebA hot, dense object produces a continuous spectrum(blackbody spectrum). A hot, low-density gas produces an emission-line spectrum. A cool, dense gas produces an absorption-line spectrum. The Interaction of Light & Matter Light & Matter can interact in a number of different ways: Matter can transmit light (glass, water). Matter can reflect light. crazy 8 children\u0027s clothing store

A continuous spectrum can serve as a backdrop from which the atoms of much less dense gas can absorb light. crazy 8 children\u0027s clothing

"WebIn physics, a continuous spectrum usually means a set of achievable values for some physical quantity (such as energy or wavelength), best described as an interval of real numbers. It is the opposite of a discrete spectrum, a set of achievable values that are discrete in the mathematical sense where there is a positive gap between each value. " - Continuus spectrum heated

WebSep 27, 2005 · Emission spectra are produced when atoms of a dilute gas are `excited' -- in effect, heated -- by an electrical current, ultraviolet radiation, or some other source of energy. Excited atoms have electrons in high orbits, and these emit photons with specific wavelengths when they jump back down to lower orbits (as explained above).
