← ScienceWhich consequence results when a high-power laser strikes optical fiber?
A)Material ablation occurs at fiber end✓
B)Increased signal transmission through fiber
C)Fiber gains super-luminal light speed
D)Total internal reflection is eliminated
💡 Explanation
Material ablation causes the fiber to degrade because rapid heating leads to vaporization, directly removing material. Therefore, ablation damages the fiber, rather than improving properties, preventing proper light transmission and total internal REFLECTION; therefore damaging the material.
