← ScienceWhich risk increases because of imperfections in interferometer mirrors?
A)Reduced interference fringe contrast✓
B)Increased instrument signal bandwidth
C)Greater spatial resolution achieved
D)Enhanced monochromatic source sensitivity
💡 Explanation
Reduced interference fringe contrast results from surface defects; **destructive interference** within coherent light is amplified because imperfections cause phase shifts, therefore fringe visibility suffers rather than resolution improving at the detector, assuming constant light.
