← ScienceWhich limitation arises because of atmospheric turbulence on stellar interferometry?
A)Reduced fringe visibility✓
B)Increased optical diffraction
C)Chromatic wavelength aberration
D)Polarization angle distortion
💡 Explanation
Atmospheric variations cause rapid changes in refractive index, inducing path length differences. This leads to **destructive interference**, therefore fringes become smeared and their visibility decreases, rather than enhancing diffraction, because coherence is affected.
