Which 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.
