  3. Photoelectric effect

  4. X-rays

  5. Laue diffraction

  6. Bragg scattering planes

  7. Bragg scattering angle

  10. 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
