Which property of the coating on fiber-optic strands makes light visible only at the ends of the strands?

A reflectivity
B absorbency
C transparency
D translucency

Answered by admin @ 28/10/2021

Answer;

A. reflectivity

Explanation;

Cladding is the glass material surrounding the fiber core. This glass has a lower refractive index and reflects the light back into the core, thus maintaining the light level over a long distance.
An optical coating is composed of a combination of thin film layers that create interference effects used to enhance transmission or reflection properties within an optical system.
