प्रश्न
Can light be ‘piped’ like sound in a doctor’s stethoscope?

उत्तर
Yes, light can be piped from one end to the other with little loss by allowing it to enter one end of a rod of transparent material. The light will undergo total internal reflection at the wall of the rod and will proceed along its axis. This actually being achieved by using a bundle of glass fibers.
