Spectra. EM spectrum and energy. Most energy?. Red Blue. Biggest wavelength?. Orange Green. Highest frequency?. Violet Yellow. Continuous spectrum. Produced by white light going through a prism Contains all colors of light, so indicates all possible energies of electrons.
E N D
Most energy? • Red • Blue
Biggest wavelength? • Orange • Green
Highest frequency? • Violet • Yellow
Continuous spectrum • Produced by white light going through a prism • Contains all colors of light, so indicates all possible energies of electrons
Differences • Continuous shows all energy levels • In line spectrums (emission and absorption), lines represent different frequencies of energies of various energy levels
Emission Spectrum • Emission spectrum produced by hot gas going through a prism http://www.iun.edu/~cpanhd/C101webnotes/modern-atomic-theory/emission-spectrum.html
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

How we know what stars/planets are made of? • element spectrums • Why we see these lines
Relation of spectra to energy levels • simple view • simple explanation
