What happens to the amount of radiation emitted by a hot dense glowing object as the object increases in temperature? Some compounds, like titanium oxide, only appear in the spectra of very cool stars. The energy causes valence electrons in these atoms to jump to higher energy levels. Each element will produce a very specific emission spectrum. Transverse motion doesn't compress or stretch waves, making the doppler effect useless. How is that related to the way astronomical telescopes work? Most stars emit the bulk of their electromagnetic energy as visible light, that sliver of the spectrum our eyes can see. Answer and Explanation: How many times dimmer would a light source become if you moved 12 times further away? No, it just keeps getting weaker with distance, but you cannot escape it. By watching the stars' spectrum, scientists could see a slight shift in where the elemental absorption lines are compared to where they should be, which told them a planet was making the star wobble. As we have already seen, the behaviour of most stars approximates that of black body radiators. a device that separates light by its wavelength and records this data. Emission spectra is used in the study of stars because when the lines emitted are studied, scientists are able to determine what the star is composed of. A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift … The gravitational pull of the moon on the Earth's hydrosphere pulls it out, while the much stronger gravitational force of the Earth pulls it back. 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. 1) How might emission spectra be used in studying stars ?
