Presentation Transcript

  1. Review – Photoelectric effect

  2. X-rays

  3. Laue diffraction

  4. Bragg scattering planes

  5. Bragg scattering angle

  6. X-ray spectrometer

  7. X-ray spectrum

  8. Why is the sky blue? • Rayleigh scattering (classical) • absorption & re-radiation of light from electrons in atom • scattered wavelength the same as absorbed wavelength • in contrast, Compton scattering changes the wavelength of X-rays

  9. Compton scattering exp.

  10. Compton exp. data
