WebAn emission spectrum occurs when the atoms and molecules in a hot gas emit light at certain wavelengths, causing bright lines to appear in a spectrum. As with absorption … WebNov 7, 2024 · Vocabulary. We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute port ions. Water vapor and dust are also part of Earth ’s atmosphere.
WebFigure 2.6: (a) When a bright object like a star is viewed through a cool cloud of gas, we observe gaps in its continuum , as depicted on the left. This is because some of the light is absorbed by the atoms, then re-emitted in random directions as indicated by the multi-colored “photons” (with arrows showing their direction of travel). http://www.infinity-theory.com/en/science/Main_pages/The_Electromagnetic_Spectrum
