  1. HW #2, Due Sep. 7 Chapter 2 P7, P12, P16, PH1, PH2

  2. This Lecture: Chapter 2 Geometric Optics Reading Assignment: All Chapter 2 By the way, what is refractive index?!!

  3. Geometrical Optics (Chapter 2) When objects are much larger than the wavelength Light Rays (Ray Optics)

  4. Shadows *Shadow-point source http://www.techxhome.com/lightsite/optics/shadows/pointShadow.html *Shadow: Extended Source http://www.techxhome.com/lightsite/optics/shadows/extendedShadow.html

  5. SUN Moon Earth Solar Eclipse: Aug. 11 1999

  6. The Lunar Eclipse

  7. Pinhole Camera *Pinhole Camera http://www.techxhome.com/lightsite/optics/pinholes/pinhole.html

  8. Depth of Image and more 2 pinholes

  9. The effect of pinhole size

  10. Diffraction

  11. Reflection *Oscillating Charge Field http://www.colorado.edu/physics/2000/applets/fieldwaves.html

  12. Law of Reflection Normal

  13. Mirrors Why metals reflect light? Why do they appear certain color? Why can we listen to radio stations far away? • Silvered and half-silvered mirrors • First-surface and second-surface mirrors *Oscillating Charge Field http://www.colorado.edu/physics/2000/applets/fieldwaves.html

  14. Grazing Incidence Reflection (glass windows, water surfaces, waxed floors, etc.) • Reflectivity (how much is reflected?)

  15. Who sees me in the mirror?! (field of view)

  16. Sun Pillars and Sub Suns

  17. Ice Crystals

  18. Sub Sun A bright subsun looking downwards from 11,000m over Italy, late afternoon 18th July 1995. The halo was intermittently visible over the southern and central parts of the country covered by a thin cirrus sheet. The halo elongated and contracted as the tilts of the plate crystal mirrors changed. Reflections from lakes and rivers shine through the cloud. Video by Les Cowley.
