Optical FiberOptical Fiber
Another interesting application of Optical fibers is the total inner reflection and the use of glass (transparent plastic rods) in which light is sent from one point to another. The pictures above demonstrate light is constricted to travel within the rod, or even throughout curves, to conclude a successive total inner reflection.

Reflection
When a light ray traveling in one medium encounters a boundary with another medium, part of the incident light is reflected. The following image can demonstrate several rays of a beam of light incident a smooth reflected surface. As you can see, the rays are parallel to each other. Whereas, the direction of a reflected ray is in the plane perpendicular to the reflecting surface.
Refraction
When the light travels through a glassy medium and encounters a boundary leading into another transparent medium, a certain portion of the energy is reflected and partially enters the second medium.
IV.-Results and Conclusions
•Information can be sent through Light and through optical fiber and that it is possible to introduce natural light indoors to help minimize cost and improve workspace.•Unfortunately there is a significant loss of information over long distances with light, but it can be made to go around corners with reflection and focused for longer distances.•The beam must be focused on to the receiver with a focal lens to be able to receive the most info possible.•It is very hard to actually pass light onto optical fiber, it must be concentrated and focused before entering the fiber.
