17. The figure above show how light reflects as it travels through fiber optics cables. The figure
show one ray of light as it travels. However, many rays of light will travel through the fiber
optic cable. As all of these rays travel through, they will interfere with each other. However,
this is a good thing. The light is very bright at the end of the fiber optic cable. What kind of
interference makes fiber optics work so well?
