← ScienceWhich destructive outcome occurs when coherent light interferes?
A)Signal nullification in fiber optics✓
B)Amplified laser cavity intensity
C)Increased photovoltaic cell efficiency
D)Enhanced Raman scattering cross-section
💡 Explanation
Signal nullification degrades transmission due to destructive interference, because waves cancel upon phase opposition. Minimum intensity arise, therefore no signal passes; rather than constructive effects that amplify signals and depend on phase coincidence in Raman spectroscopy.
