← ScienceWhich risk increases when cross-polarized filters poorly align?
A)Reduced signal contrast✓
B)Increased thermal expansion
C)Harmonic current distortion
D)Elevated resonance frequency
💡 Explanation
Reduced signal contrast occurs because imperfect alignment obstructs complete destructive interference via polarization, resulting in partial transmission of light that reduces darkness and contrast, therefore contrast is reduced rather than alternatives under ideal optical conditions.
