Presentation Transcript

  1. Review – Blackbody spectra Rayleigh Jeans formula • Stefan-Boltzman law: R =  T4 • Wien’s displacement law: mT = const.

  2. Review –X-ray spectra Duane-Hunt rule

  3. Review – Compton scattering

  4. Dispersion of Light Snell’s law of refraction: n1sin θ2 = n2 sinθ2 Dispersion: n() different speeds - disperses (separates) light - spectrometer - can also use diffraction grating Why slits & lens?

  5. Hydrogen spectrum Emission spectrum Absorption spectrum

  6. Atomic spectrum
