← ScienceWhich risk increases when adaptive optics fail during propagation through atmospheric turbulence?
A)Increased beam divergence✓
B)Reduced photon energy
C)Chromatic aberration increase
D)Polarization state change
💡 Explanation
Adaptive optics correct distortions via wavefront manipulation; when they fail, imperfect correction causes increased beam divergence due to residual phase distortions. Therefore, the beam does diverge, rather than maintaining coherence because of lack of phase compensation.
