← ScienceWhich consequence results when radio waves pass through atmospheric ice crystals with uniform alignment?
A)Signal power exhibits direction-dependent differences✓
B)Temporal dispersion uniformly affects signals
C)Minimal effect due to molecular transparency
D)Frequency-dependent refractive index deviations appear
💡 Explanation
Radio wave propagation through aligned ice exploits polarization; differential attenuation results because absorption varies based on wave orientation relative to the crystal axes. This causes anisotropic transmission of polarized waves; therefore, signal power becomes direction-dependent, rather than undergoing simple absorption.
