2011 년 11 월 4 일 (11 일 수업 보강 ) 제 9 장

 Light Waves  Mirrors: Plane and Not so Simple  Refraction  Lenses and Images  The Human Eyes  Dispersion and Color  Atmospheric Optics: Rainbows, Halos, and Blue Skies

 Devices using optics and phenomena ◦ Cameras, telescopes, LCD, rainbows, soap-bubble iridescence, sundogs

Color Red (750nm) Orange Yellow Green Blue Violet (400nm)

 Specular Reflection  Law of Reflection ◦ The angle of incidence equals the angle of reflection  Diffuse reflection

 Half-silvered mirror

 Spherical aberration

 0.002mm error

 Law of Refraction ◦ A light ray is bent toward the normal when it enters a transparent medium in which light travels more slowly. ◦ A light ray is bent away from the normal when it enters a transparent medium in which light travels faster.

 Spherical aberration  Chromatic aberration

 Shorter wave travels slower
