Elliott+Fiber+Optics

Fiber Optics are becoming increasingly important in the computer and communication worlds of the modern day. A fiber optics cable is essentially a glass cable filled with multiple fibers that can transmit light information at great speeds. It relies almost solely on total internal refraction to bend light around corners and obsticles that the cable may run through. It does this because every time the light hits the edge of a fiber cable, it is totally internally refracted from that fiber material, which allows the light to travel down the fiber optic cable. It works on the basis that the angle of the light is always greater than the critical angle, which therefore allows all the light to be reflected within the fiber itself, which again allows the light to run down the optic cable.
