← ScienceWhich outcome results when atmospheric conditions suppress a microwave communication relay?
A)Signal fading increases exponentially✓
B)Wave interference creates blind spots
C)Antenna impedance becomes perfectly matched
D)Refraction enables longer transmission range
💡 Explanation
Signal fading increases exponentially because atmospheric temperature inversions or high humidity can cause atmospheric ducting, leading to destructive interference via multipath propagation; therefore the signal strength at the recepter attenuates rapidly, rather than a simple blind spot.
