29.12Total Internal Reflection
Optical fibers, sometimes called light pipes, are transparent fibers that pipe light from one place to another.
They do this by a series of total internal reflections.
Optical fibers are useful for getting light to inaccessible places.
Mechanics and machinists use them to look at the interiors of engines, and physicians use them to look inside a patient’s body.
28.1 color, how vision is corrected and rainbows.The Color Spectrum
When sunlight passes through a prism, it separates into a spectrum of all the colors of the rainbow.
Dispersion of white light into component colors
A prism disperses white light into its primary frequencies of color
