← ScienceWhich consequence occurs when a laser beam encounters imperfections within a fibre optic cable?
A)Signal amplification using Raman scattering
B)Wavelength shift from the Doppler effect
C)Loss of intensity due to scattering✓
D)Increased coherence through phase conjugation
💡 Explanation
Imperfections trigger Rayleigh scattering because they disrupt the refractive index, therefore energy is redirected from the original beam path, rather than experiencing amplification or phase changes; those require completely different non-linear optical mechanisms.
