WebSep 27, 2005 · In contrast, an emission spectrum, like the one in the middle of Fig. 5, consists of bright lines or bands on a dark background. 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.

Spectroscopy can be very useful in helping scientists understand how an object like a black hole, neutron star, or active galaxy produces light, how fast it is moving, and what elements it is composed of. Spectra can be produced for any energy of light, from low-energy radio waves to very high-energy gamma rays. … See more White light (what we call visible or optical light) can be split up into its constituent colors easily and with a familiar result: the rainbow. All we have … See more The resultant rainbow is really a continuous spectrum that shows us the different energies of light (from red to blue) present in visible light. But the electromagnetic … See more The science of spectroscopy is quite sophisticated. From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the … See more WebLine Spectra. Although objects at high temperature emit a continuous spectrum of electromagnetic radiation (Figure 6.2.2), a different kind of spectrum is observed when … WebThe spectrum formed is an emission or bright line spectrum, as shown by the middle spectrum in Figure 1.
