  1. Spectra

  2. EM spectrum and energy

  3. Most energy? • Red • Blue

  4. Biggest wavelength? • Orange • Green

  5. Highest frequency? • Violet • Yellow

  6. Continuous spectrum • Produced by white light going through a prism • Contains all colors of light, so indicates all possible energies of electrons

  7. Continuous spectrum

  8. 3 types of spectrums

  9. Another view

  10. Differences • Continuous shows all energy levels • In line spectrums (emission and absorption), lines represent different frequencies of energies of various energy levels

  11. Emission Spectrum • Emission spectrum produced by hot gas going through a prism http://www.iun.edu/~cpanhd/C101webnotes/modern-atomic-theory/emission-spectrum.html

  12. Absorption Spectrum • Produced by white light passing through a cold gas and then a prism http://www.museevirtuel-virtualmuseum.ca/edu/ViewLoitDa.do;jsessionid=55F3241793B573106876E2154526ED6D?method=preview&lang=EN&id=19930

  15. How we know what stars/planets are made of? • element spectrums • Why we see these lines

  16. Energy Level Diagram

  17. Hydrogen line spectrum

  18. Relation of spectra to energy levels • simple view • simple explanation

  19. Hydrogen spectrum
