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
