PHY 102 Lecture Notes - Lecture 20: Double-Slit Experiment, Corner Reflector, Refraction
Document Summary
Visible - 4 x 10^-7 to 7 x 10^-7 m. 4 x 10^-7 to 7 x 10^-7 m. Red, orange, yellow, green, blue, indigo, violet. Einstein was able to explain planck"s effect. Light is a wave and a particle. Violet slower than red > violet bends more. Red will always be at the top of a normal rainbow, violet will be at the bottom. Angle of reflection = angle of incidence. From smooth surface - single normal - reflected rays. From rough surface - many normal - reflected rays different direction. Any light hitting the reflector is reflected 180 degrees. Amount of direction change depends on difference in speed. Ration = speed of light in vacuum/ speed of light in medium. N: always going to be bigger than 1. The slower the speed of light, the larger index of refraction.
