← ScienceWhich mechanism inhibits image clarity when atmospheric turbulence disturbs electromagnetic waves?
A)Chromatic dispersion alters spectral components
B)Scintillation causes refractive index fluctuations✓
C)Diffraction minimizes propagation direction changes
D)Attenuation uniformly reduces signal amplitude
💡 Explanation
Scintillation disrupts image clarity because temperature gradients cause random variations applying the Huygens–Fresnel principle; therefore propagation is perturbed rather than chromatic dispersion, which depends to a prism, because all wavelengths bend similarly.
