← ScienceWhich consequence results when increased atmospheric ionization in radio propagation channels?
A)Enhanced signal ducting occurs
B)Attenuation of signal lessens
C)Faraday rotation amplifies dramatically✓
D)Thermal expansion reduces markedly
💡 Explanation
Increased atmospheric ionization boosts the electron density, therefore augmenting Faraday rotation because the interaction between electromagnetic waves and charged particles modifies wave polarization, rather than causing signal ducting or reduced signal attenuation.
