If you shine a light through an optical fiber, why does it comeout the end but not out the sides?(a) It does come out the sides, but this effect is not obviousbecause the sides are so much longer than the ends.(b) The sides are mirrored, so the light reflects.(c) Total internal reflection makes the light reflect from thesides.(d) The light flows along the length of the fiber, nevertouching the sides.
