Question
Fiber Optic Distances
When light rays travel down optical fibers, they don't follow a perfectly straight path. That means the light has to cover a little extra distance compared to the straight-line distance from one end of the fiber to the other. Suppose a light ray enters a fiber of diameter 59 mm at an angle of =27 degrees with respect to the fiber walls. How much actual distance will the light ray have to travel for every meter of fiber it moves along?
