Law of Reflection Normal
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
Grazing Incidence Reflection (glass windows, water surfaces, waxed floors, etc.) • Reflectivity (how much is reflected?)
Who sees me in the mirror?! (field of view)
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.
