We all know that electrons in an atom or a molecule absorb energy and get excited, they jump from a lower energy level to a higher energy level, and they emit radiations when they come back to their original states. 42:14. Last Updated on May 3, 2020 By Mrs Shilpi Nagpal 7 Comments. Tuesday December 11, 2007 The focus of this lecture is to review emission and absorption spectra by looking at the theoretical projection of the Earth’s spectra and how it changed over time. Shape and energy of atomic orbitals 13. Look at the two figures below. Home Page. – continuous spectrum • light of all colors & wavelengths • follows thermal distribution • obeys Wien’s & Stefan-Boltzmann Laws. low density . UPSC. Spectroscopy is the study of emission and absorption spectra. Hydrogen Spectrum : If an electric discharge is passed through hydrogen gas is taken in a discharge tube under low pressure, and the emitted radiation is analysed with the help of spectrograph, it is found to consist of a series of sharp lines in the UV, visible and IR regions. Engineering. Hydrogen Emission Spectrum. Line emission and absorption spectra Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. Line spectrum of hydrogen and its explanation 11. NEET. It is the exact opposite of the emission spectrum! Some compounds, like titanium oxide, only appear in the spectra of very cool stars.
