which property of the coating on fiber - optic strands makes light visible only at the ends of the strands?\nreflectivity\nabsorbency\ntransparency\ntranslucency
Answer
Answer:
A. reflectivity
Brief Explanations:
The coating on fiber - optic strands has high reflectivity, which causes total internal reflection. This keeps light confined within the fiber and visible only at the ends. Absorbency would absorb light, transparency and translucency would not confine light to the ends.
