Which consequence arises when microwave signals experience multipath propagation?

A)Signal strength experiences constructive interference
B)Subharmonic distortion increases measurably
C)Antenna impedance approaches zero uniformly
D)Wave velocity shifts towards lower rates

💡 Explanation

In multipath propagation, signals reflecting off surfaces arrive out of phase; constructive interference occurs because the superposition principle dictates fields sum, therefore boosting signal at specific locations, rather than creating any velocity change
