← ScienceWhich effect arises when microwave transmission encounters rapid atmospheric temperature inversion?
A)Beam refraction causing range errors✓
B)Signal amplification due to wave superposition
C)Frequency shift from Doppler broadening
D)Polarization change from Faraday rotation
💡 Explanation
When microwaves meet a rapid temperature inversion, differential refraction occurs because the varying air densities alter wave speed progressively across the beam, bending the wave path, leading to range errors. Therefore beam refraction results, rather than amplification, frequency shift or polarization change, which depend on other mechanisms.
